Thanks for the feedback! Guessing the climb on the left got you, that is tough for sure. I have a hard time with the keyboard, feels easier with a gamepad. Having to climb back up is frustrating. If you small jump and have great slow fall timing you can make it a single jump. There are 10 levels, this should probably be 8 or 9 if not refactored a bit. Glad you didn't get stuck on a wall jump level!
Thanks again for playing and especially leaving feedback :)
