This one is really cool.
Loved the mechanics and the whole idea, the level design was nice and I'd love to see this game progress.
I think this game has huge potential, but clearly not as a block game. The game will really look nice in future with proper art assets (if you have some) and a full fleshed out idea.
I had some bugs (if you press windows key it freezes until restart, the game didn't seem to do anything when I got out of the cave and transformed back into a human) but those are expected.
Really want to see what this game idea becomes in the future, nice!
