Really fun when it works! Both the player and the level being able to change in size was a nice twist, though I didn't realize you could grow bigger for a longer part of the game than I would like to admit, but after that things were pretty fun!
The things that stand out to me most are the physics being a bit floaty and the lack of checkpoints, since I found myself having fun and getting into the groove with puzzles, before dying and losing all my progress, which ended up being a bit frustrating.
In all, my high-score was 23/69 screws. To pay my compliments, the aesthetics and overall visuals are really pleasing; the puzzles and alternate routes are interesting and fun to explore; and the mechanics fun to play with, although not as snappy as I would like. Nice work here!
