I like the art and the intro.
I hate the control scheme though. All the controls are clustered too closely to the left. It would have been better if the arrow keys are also usable as movement controls. My right hand is left rather idle during the game when it could have been doing something else like controlling the movement. Dashing often interferes with my movement (nevermind, I'm a dummy. You can use Right Shift to Dash).
Also the wall jumps. I don't like them. I don't know if that's the standard controls for wall jumping since I don't play too many truly hardcore platformers, but I loathe them. Either it's a skill issue or a design issue, but I bet it may be the former.
