Cool game! It starts on an easy side, but on later puzzles the reasonable difficulty kicks in. I liked the puzzles in the end! Also great design on gradual introduction of mechanics and postponing restart mechanic "Q" to 2nd level simply by making level 1 not failable, I respect that.
I really liked the visuals and style, attention to detail is stunning, removing block puff animation is my favorite :)
Sorry to say that but I found a bug:
Soo now I'm not sure if I completed all challenges fair. Overall that's a great game in this jam, congrats!
