Fun game! Fun sounds and cute style! I like that you didn't make the puzzle pieces too "picky" so that you can grab them from quite far away so the levels feel like playgrounds where you can throw stuff around if you want :D good ending too!
Improvement ideas:
- Add drop shadows so it's easier to climb ramps without falling and also to see where the blocks will land when dropping them
- Faster grow and shrink, it's kinda annoying to wait even a full second when you hold q or e.
Fun game, thank you for the experience!
