Controls are in the game, but you can read them here too:
Wall jumping has been made simpler so it's easier on your fingers.
For wall jumping you can just hold down one direction and spam jump. The normal way works too, but it's harder.
For example, this is just holding down right and spamming up:
Arrow keys - Move/Jump
X - Invisibility
C - Smoke Bomb
Left Stick - Move
A - Jump
Left Bumper - Invisibility
Right Bumper - Smoke Bomb
