Hi, I'm not sure if you are aware of these, but it is possible to jump over high walls by doing the backflip repeatedly against a wall. Also, another thing I noticed was that sometimes the backflip makes the player jump really high up (like 5x the normal jump) - this usually happened when touching a wall or a corner when backflipping.
First thing is actually a walljump, which is a secret ability I added for sequence breaking. Second thing is a glitch that might never be fixed. I know the walljump isn't the best walljump, but I wanted it to be secret, which is why it feels like a glitch. At some point I will come back and fix old bugs, but right now I just want to work on other things. I'm lazy :(
