I appreciate the feedback and I confess that the game really should have a way to remap buttons, but wouldn't it be harder to press E and D together rather than D and spacebar?
well, for the most part, no. If i'm on the ground I can turn using the mouse, without needing to press D or A at all. And in the air, I can press E and D with the same finger together or hold them down together and that's still easier than hitting spacebar with my thumb really fast while pressing W.
