Thank you very much for your feedback, and we're glad you liked the game!
Truth be told, on the topic of the wall jumping, originally jumping up walls was way easier but then someone suggested that I instead have the wall jumps inherit your momentum. Now I'm not entirely sure about if my implementation was exactly a great one, as LITERALLY TODAY I finally found a set up that lets you scale walls with the current system.
All of that said, if we do anything more with this game, we'll definitely tune the wall jumping to try to get them feeling good and to allow it to enhance movement and scaling up walls.
