We are aware of this bug, but it is not a simple fix. We plan to remake the game in godot, and improve and bugfix the experience, I hope you'll stick around for that :D For the bit where you got stuck, you can wall jump if you turn away from the wall and jump, and to beat the section, you have to grapple and wall jump. The wall jump feels a bit jank, and we are aiming to implement a better wall jump in the godot version!
