I dig it.
The platforming feels responsive. The puzzles are fun.
The hitbox is kinda janky at times, which lead to some frustrating moments where I collided with a wall when I shouldnt had to or died to a projectile when I was on what it seemed safe ground. But that's totally forgiven for a gamejam.
I would make the scaling less granular and make the size levels fewer but more unique in order to be more clear what size I should have for resolving the puzzles, aka how big for going through this corridor/successfully jumping a trampoline.
Anyways, great entry.
