I really wanted to finish this game but during the climb after falling down and having to repeat the wall-jump section 4 times I gave up. The suggestions twiggy88 gave below are really good.
Understandable, a lot of people seem to be having a hard time with the wall jumps. If you don't press and hold in a direction and just press the jump button it works perfectly but it isn't the first thing players think of xD; Thank you so much for the feedback! I will pass it on to the coders. <3
