Good job! I had 3 problems, though. Theres a little bit of input lag, which makes jumping difficult.
Also, I'd suggest getting rid of the rounded corners on the walls, or changing the way the player interacts with them. I got stuck several times, and the dash would unstick me occasionally, but not always.
The last thing is that the wall grab just stopped working at some points, so you may want to look into that.
It's still beatable, though, and I'd love to see the difficulty ramp up even further in new levels.
