The sound design felt creative and the art was cute. Puzzles were solid. Some were a bit easy, but a some of the last few made have to retry a couple times. Definitely a simple concept that you could easily expand on with more puzzle variations. Good use of the block placements.
The white text for level completion made it impossible to see what the buttons were and more tedious to end a level, and the first stage has a glitch where the level complete text disappears immediately after touching the flag. But the game was ultimately still playable and that's all that matters for a jam.
