Hi, I've been playing the game all night, love it to bits, thanks so much!
I love what feels like in part an homage to Mario 64, and maybe contrary to some, I'd like to suggest taking some inspiration from M64's camera, in terms of the C-left and C-right buttons. I think it'd be great to be able to rotate the cam mid-action without taking my thumb off the jumpies.
Super love the game. Would pay money. Will probably start looking at what it would take to mod some levels, or even make a PR for this feature myself! :)
