pretty good game. i have some notes but not many:
when your big and hit a spike from the side you die(might be a glitch)
its sometimes a bit hard to judge how far away a platform is when your small and low on time
I feel like the big size and small size have relatively the same speed. it would have been neat to see a slower speed for the big one
maybe its just me but I don't always change size in the air or while moving when I wish to
but all in all its an astounding game for the 48 hours you say you spent on it. your game far surpasses mine and I wish you the best of luck.
