Hi all,

It’s the second Saturday of the month which means its time for a now Kana Quest Devblog! Last time I said we were going to unpack several choice levels from the game, and what makes them good levels. And that’s exactly what we are gonna do. So

Now if you’re new here, Kana Quest is a cross between dominoes and a match-3 game that teaches you to read Japanese. You match sounds between letters, and when all letters are connected the level is complete.

This is the fourth level in Kana Quest and is the first level that consistently stumps players. Up to this point levels have been made to get the player used to moving Kana around, and understanding that stone Kana can’t move. This is the first level that actually tests the player’s understanding of how Kana match. So, how is this achieved? It is achieved by asking the player two simple questions; “In what order do the three movable letters need to be in so they all match?” and “Now that I have the order of the three movable Kana, how do I position them so that the one stone Kana also matches?”. These might seem like very simple questions, but there are a few factors that make them a lot harder than you might suspect. The first thing is that, this is the first time the player has had to order 3 Kana. Second is that all of the Kana have been deliberately placed so that the player has no matches, this means they are effectively starting from scratch. Thirdly the number of potential configurations is way higher than all levels up to this point. Finally, because the stone Kana is placed in the centre of the board, it means there are a total of 4 different correct solutions. But it doesn’t guide the player to any of those solutions in of its self. This forces the player to pay attention to the sounds of each Kana, and use that information to solve the level. Not use the shape of the level to tell them the solution. This is not to say that using the shape of the level to guide the player is a bad thing. It usually is a great thing to do, especially for more complex levels. But the purpose of this level is to test the player’s understanding of how Kana match.

The next level I want to look at is the final level of world 3. So where the previous level was testing the players understanding of how kana match, this level is testing the players understanding of one directional kana. One directional kana, are a lot of fun to play with because of how the restrict the number of potential arrangements of the kana. This is useful because it can be used to signal to the player the shape of the solution.

This level is set up so that there are only 5 possible positions for each row that could be the correct position. This helps the player start with a very strong sense of how to solve the level. But there are two curve balls in this level. The first is the one normal Kana (の) at the top of the level. Because this kana could potentially go anywhere in the level, the player has figure out how to best utilise it. The second is the one directional す on the right of the level. This says to the player that one of the three rows to the left of it need to be all the way over to the right, but you need to figure out which it is. When these two elements are mixed with each other they create an ideal puzzle. A puzzle where the player has a strong idea of their goal, but they still have to work for it. One last small detail from this level that I like is the blank one directional kana. These serve to prevent the player from trying red herring solutions. Red herring solutions are fine to have, but each red herring still needs to lead the player towards the solution. If a red herring just leads the player down the wrong path and leaves them at a dead end, you need to get rid of it, as it will only aggravate your player.

So for the last level that I want to talk about today is from the ninth world. If the first is an example of a good introductory level, and the second was a good intermediate level. This is a good hard level. So what makes this a good hard level? Well, honestly the same thing that’s made the previous two good; You know what your goal is, but you don’t know how to get there. This level achieves this with the り in the centre of the level. Because it is central, and it cannot move because it is a stone kana, the first thing the player will do is look for the other kana that match with it. In this level there is the transform kana (the rainbow coloured one), the ice ろ, and the paralysis ひ. The paralysis ひ has to end up to the right of the り because it can only be moved once before turning to stone. This leaves three spots left for the ice ろ. This puts the player on a strong starting direction for the level. But the thing that makes this level so challenging is that because of how ice, paralysis and one direction kana work, if the player makes moves carelessly they will trap themselves and be unable to complete the level. Once again, the needed end state is easy to determine, but how to get there is the challenge. The only real difference between these three levels is that they make the “how to get there” part more complicated.

Anyway, that’s the Devblog for this month. Hope you enjoyed. I’ll be back next month on the second Saturday of the month. I haven’t figured out what the topic is gonna be, but ill figure something out. Until then, take care!

First thing’s first, I know I missed the January devblog. I’m sorry it wont happen again. But… it’s here now, and it’s a new year, which means this is the first devblog for 2019! This is going to be a big year for Kana Quest as this is the year we are going to release! Knowing the end is in sight is a strange feeling as I’ve been working on Kana Quest for the last two years of my life. But I hope you all will be there with me as we run headlong down this final stretch!

So what does this “final stretch” look like in terms of development? Well for me personally that means making all the levels. I had spent most of 2018 finishing the art and making all the visual assets, but in terms of gameplay, very little was being made. But now that I’ve finished all the visual assets and Reuben my programmer has finished programming in each mechanic, I am able to churn out levels very quickly. How quickly is that? Well since last month’s devblog, world 5, 6, and 7 now have all their levels made. Of course these levels still need play testing before they are 100% good to go, but they are playable, and reasonably balanced.

So, seeing as levels are all I have been doing this past month, I’m gonna tell you how I have been making them. And some of the weird things I have to pay attention to when I’m making levels.

The first thing I do when I start making a level is I figure out, how hard I want this level to be, and what kana I want the player to see.

flowchannel

Sorry if this is a bit too game design 101 here buuut… This is the flow channel. Flow is that feeling where you are in the zone. But getting the player into the zone requires very careful balance from the game designer. So something I’m sure you will notice when you play Kana Quest is that every three to five levels will build in difficulty, only to drop back a bit and then continue ramping up in difficulty.  The reason you do this, is that it’s just more fun for the player.

In Kana Quest there are a few different ways you can control the difficulty of any given level. They are:

  • The amount of Kana in a level
  • Size of the level.
  • Potential board state permutations
  • Number of potential solutions
  • Complexity of solution.

So lets go through each of them. And first up is the amount of Kana. So in my experience, you have a hard cap of about 14 -16 different Kana in a level. Why is this? This is because past this number, there is too much information for the player to comprehend. And personally, even I can’t process levels with this many Kana. It’s also a difficulty that isn’t a lot of fun for the player. Solving the puzzles is fun, recognising kana… not so much.

The size of the level like the amount of kana, also has a hard cap. This time its not so much about overwhelming the player though. The largest you can make a level in Kana Quest is 7×4. This is simply because if you make the level any bigger, it will not fit on the screen. I know that sounds silly, but due to the way pixel art works, there is no easy way to just “zoom out” without also causing a lot of pixels to bunch and stretch. But honestly, most of the time this is plenty to work with. If you are smart about how you construct things this is not actually as bigger constraint as one might think it is.

What I mean by “potential board state permutations” is how many possible unique configurations can be made in any given level. So for example.

These two levels have the same kana, and the same starting positions but the first level is significantly easier than the second because the number of possible configurations of kana has been significantly reduced. Forgive me if my maths is wrong but the level on the left has only 120 unique board positions, whereas the level on the right has 362880 unique board positions. And while an advanced player can see through all the unnecessary information in the second level, it doesn’t actually make the puzzle any more fun for the advanced player because in both scenarios, the solution only requires two moves. So while you are giving advanced players a disappointing level, you are giving new players a level that is so information dense they will almost always solve the level by brute forcing the solution. What I’m trying to convey here is that when designing puzzles you need to control the amount of possible states so that you can guide the player to the solution. Now for more advanced levels its fine to offer levels that are more open ended, but you do need to be very sparing with how you do so.

Next up is the number of potential solutions. This category is a tricky one as personally I feel as though levels with multiple solutions make the level harder, not easier. Why you might ask? Well because it means that your players are less guided towards the optimal solution. It means they are more likely to get caught on unintentional red herrings. It also means that if the player wants to get a gold medal for a level, but they have only ever completed the level using an alternate solution that is more move intensive than the planned solution, they could spend way too long trying variations on the “wrong” solution. Really this is a side effect of having too many potential board state permutations, but every now and again its fun to have levels that offer multiple answers. Lots of levels in Kana Quest only have one solution, and lots of levels have multiple, the important thing is using this technique intentionally.

The final technique that I can use to control the difficulty for the player is probably the most important one. And that is complexity of solution. If the solution only requires two or three moves, its not a particularly complex solution. This usually means that the level isn’t super difficult. However, completion critical moves increase the complexity. A completion critical move is a move that if not made, the level cannot be completed.  Of coarse this can then be balanced with previous techniques. For example.example3

This is a level from world 1. And is in my opinion one of the best levels in that world. This has a very low complexity of solution, but in contrast to the all the levels before it, it has a slightly higher difficulty. But that difficulty comes from a larger number of potential configurations, multiple solutions, and a larger level size. The result is a level that isn’t too difficult, but does force the player to stop and think about the solution. But as the game ramps up in difficulty, ramping up the complexity of the solution is usually the safest way of doing so. Why is that? Well, it means you can control the amount of information you throw at the player to a far greater extent. Remember, you don’t want to overload the player with information, if they do they just start brute forcing the puzzles and have a bad time.  So an example of a good level made by giving the player a complex solution is this level.examplesolution

The reason this level is good is because it requires a good amount of moves to complete, and there are only two completion critical moves required (using the Slime Kana on the correct Kana), and those moves can be executed by the player at any point. Whereas, here is a level that has gone way too far on the complexity of solution.example3

This level is way too hard and is to date the most difficult level I have made. And the reason is, that every singe move in this level is a completion critical move that requires being done in the exact right order. If you make one wrong move, you cannot complete this level. The fact that this level has a relatively constrained number of possible configurations is its only saving grace. And I wouldn’t be surprised if I remove, or rework this level before the launch of the game.

I think the real take away from this blog if you are making, or thinking of making your own game is; What are the different vectors for making a game difficult? Are there enough? Are there too many? What are the implications of using one of those vectors? What are the implications of using multiple of those vectors at once? How far can one push any and all of those vectors before a game becomes impossible? And most importantly, at any point in a game, what vectors of difficulty does the situation call for?

Anyway, these are the things that I’ve been thinking about for the last month or so. I’ll see you next month. If you have any questions about game difficulty or you disagree and you want to start a discussion, feel free to leave me a comment and we can have a chat. Until next month, take care.
