We definitely ran out of time aesthetic-wise on prettying up the different areas. Neither of us are super experienced with pixel-art, and are working on honing those skills.
For the controls, we are definitely planning to incorporate custom controls, as I have received feedback that some folks aren't WASD gamers, and much prefer the arrow-keys for platformers. The idea with making the dash on a separate hand was for some intensive platforming jumps, to spread the carpotunnel-button-mashing to both hands.
Thanks for playing and providing great constructive feedback!
