Your game has a very cool mechanic. It is quite difficult, I couldn't get far as my jumping skills are lacking. Would be nice to have some background music because playing this in silence feels a bit gloomy.
I would suggest adding some instructions to let the player know that they shouldn't be touching the walls while jumping. I had no idea and was trying to wall jump, until someone from my stream chat told me what I need to do.
Overall, really cool and challenging game!
