I'm glad you liked it :D

For the wall jump:

Basically check if we are running on the wall and we press the jump. Then, check which side we are wall running on and get the normal of the wall (I'm using 2 rays that extent out horizontally from the player on opposite sides). Then, get where our player is facing but take out the vertical direction. Last, apply to velocity by adding the force to push away from the wall, the force to jump slightly up from the wall, and the force that launches us forward based off where we face. And each of these forces are multiplied by a multiplier for adjustment.
