A very nice puzzle game, that at some points feels a bit like a rage game - but in a positive way, since it feels like some of the challenges are annoying / rage inducing on purpose.
I especially liked the water spreading mechanic. The in-game tutorial was very nice.
And the music! It's a perfect fits to a puzzle game!
And the amount of levels! I find level design to be the most annoying and time consuming part of making games, so I appreciate the effort that resulted in so much content!
