This artstyle is really cute! I love how the menus are actually baked into the game's cutscenes (which had some good humor), and the physics were also really consistent for a jam game.
One little bit of criticism I have is that the puzzles feel a little too "open"? As in, I usually don't find myself thinking strategically about where I'm placing things, and found myself beating levels by just throwing a bunch of blocks into a level to generally push the player towards the goal. I think with some tighter level design, this could be a really good puzzler
