This is a great short puzzle platformer. I actually liked the style where everything was just a black box instead of a sprite - it made it more abstract and maybe less jarring to imagine a character changing size a bunch? Though, I don't know what the original artistic intent was. I think it's good as it is. With more puzzles and mechanics, this would be a fun full game.

I like how the "YOU WIN" screen could be made out of several instances of the character. Jumping was a little wonky and inconsistent between the heights, I'm guessing that's related to not scaling physics actions with the frame rate. Cool game!

Gameplay was interesting, but a little on the slow side, 

for example the diamond you had to pick up to open up a pathway moved incredibly slowly, and some free pathways had snake paths which just padded playtime.

Besides that I really enjoyed the actual mechanics, and I though the puzzles were well designed!

Too bad the assets didn't load in, but I thought the game was charming nonetheless!

For all its simplicity, it's surprisingly morish.

The horizontal and vertical scaling is a bit sluggish; perhaps have that accelerate as the keys are held down.
