Good game! I think that the level progression is very well done - the game introduces new mechanics and tests the player's knowledge of them in a thoughtful way, I very much like that. I think that some levels are maybe too hard and too "finnicky" in some unpredictable and un-fun ways (like: I already figured out how to beat a certain level, but I keep failing because of my bad motor skills). I'm also not a big fan of the visuals themselves. Overall, I found the core mechanics very interesting and had a fun time with this game.
