Really interesting game! I was a little confused with the controls, they weren't that comfortable to lay my hands on and some were not that useful, but that's part of the game with everything about losing them as you go I guess. Good game!

B J and M were awkwardly placed in my right hand, and Shift was weird for being the only "special" control that I did with my left hand. Maybe stick with arrow keys for movement and use C/X/Z/Shift for the special ones? Though keyboards with small arrow keys would struggle more. Or WASD for movement and HJKL for special ones? Not sure.
Also when I clicked Restart the music went away.
