the game is good but if I may argue something, I feel it lacks "progress".
You unlock everything in the first few games and apart from a couple missions with ghosts your build doesn't really matter. 4/5
level 24 is, as far as I can tell, completely impossible or based on random quantum fluctuations, I've tried to copy what the walkthrough does a dozen times :(
good game, i'd suggest two things: it wasn't clear to me that the colored markers only meant "same group" and not also "folds here". Maybe fill the whole square then halve and quarter?
Also it would be cool to hve an "easy" mode which signals when one net is correct, even if the others aren't in yet
