Is wall jumping possible? Would I just set it to jump from ground? Does a vertical surface trigger this? So many questions!
You should try moving the game direction to something like what skill wave did that enabled the center of world gravity to be on a wall. I am not sure if there is a way to then change that center of gravity with a gameplay action, but if there is, then that would be cool.
that to which things will fall in skill wave, the character, if you don't tap to jump, falls to the left
