Hey, thanks for playing and thanks for all the feedback!!!
I was one of the programmers and we did notice the wall jumping bug and we're already working on fixing that for a little polish build when the rating period is over. We just didn't manage to get that done in time for submission.
I'll ask the artists to make an alternate version of the shift button too we can put in to make it a bit more clear what button you're supposed to press.
Again, thanks for playing and thanks for all the feedback!!
