hey fruit friend, dutch friend here!
I played it and I liked it. I did use a program to map keyboard to controller to play on that.
I’m quite sure you’re going off super mario land physics here (well, not just the physics, but I’m not complaining :). I would still consider slightly lowering the acceleration while walking off a ledge and maybe having like 1 frame of coyote time, even tho SML doesn’t have that. Even without that, I still enjoyed hopping around!
