"Scale to move" is a novel take on the theme. I like how it makes a movement and navigation a core part of puzzles. It reminds me of snakebird in that regard.
The puzzles are great and it's impressive that you've managed to make so many puzzles within the jam timeframe.
My only criticism is that it's a bit finicky. Thankfully you restart without losing much progress if you die. Though in the levels where you push boxes, you can sometimes push it into an unwinnable state requiring a full reset. If you expand the game in the future, my suggestion would be to add a separate slow-mo button to make precise mid-air maneuvers easier. Or an undo button.
The lo-fi style is very pretty with post processing. It nails the retro vibe.
Overall it's a great entry!
