This game was a bit too hard for me, so I couldn't finish unfortunately.
The control binding system may need some more refinement. Remapping controls was too cumbersome, so I often just stood in place until my keys re-enabled since the time penalty wasn't so severe. I think I waste more time if I try to fiddle with the controls than I do if I just stand in place and wait for the key to re-enable.
I was hoping I could use my keys more efficiently by connecting them to two actions. I was disappointed when I found out that drained the key twice as fast. I feel this could have added more depth to your game play.
I really liked your artwork. You used a nice color palette and all your assets look super clean. Good job!
