Thanks for the feedback! I really should have some kind of quick setup for doing key customization, it's just something I never really implemented for a jam game. Will definitely do so if I expand on this. Out of curiosity, what kind of keyboard do you have? I've never heard of a keyboard with space on the right side.
Also the game should work using W (or up arrow) as a jump key, I just only mentioned it in the description (whoops)
