I just finished solving the puzzles. Overall I really enjoyed the game.

The only thing I did not like was that for certain puzzles, such as the Ying-Yang one, coming up with an idea that will solve the puzzle is quite straight forward, but figuring out the parameters you used for some of the curves can take a long time.

The Ying-Yang problem has no hints and I had to use two different sine waves for the upper half and the bottom half of the screen, just because I couldn't guess which one you used. I also tried solving the "spiraling into control" one without looking at the hints, and was unable to.

Thanks, and really happy you enjoyed it!

Yeah, I know that's an annoying issue. I've been trying to think how to implement a good fuzzy judge, but so far everything I have will either forgive mistakes in small but important components or require a major restructuring of the game. Would be happy to hear if you have suggestions for that :)

I would just make sure everything uses simple parameters. The "Making Waves" puzzle is easy to figure out by trial and error, because the values to guess are simple.

One thing that is particularly hard to guess is the "Spiraling into control" puzzle, because the parameters you have to guess are tied to the value of the time increment for drawing the curves. The parametric equation to that curve is currently :

x(t) = 8 + t * cos(A * 2 * PI * t)

y(t) = 8 + t * sin(A * 2 * PI * t)

where A is the ratio between the `t` increment (0.4) and the angle increment (PI/36) (or is it the other way around?). That ratio is just too hard too guess. I would just rewrite the solution to make the constant A easy to guess, so that people writing code with different increments and just playing around with the constant can eventually figure it out.

The Ying-Yang one is harder to simplify, because the result will not look as good. Maybe add an hint?

Thanks a lot for the suggestions!

I added hints to the Yin-Yang one. Regarding the spiral, I get what you say, but I've found that more convenient parameters yield spirals that I like much less. I broke down the hints so that it's less spoiler-y, hope this makes for a better experience.
