If you have the UPE, you can figure out how to do this. But you could do it in PB by creating a new keybind that when those buttons are pushed, then the character will disappear and be disabled. Then spawn an enemy over the character with a collision set that is just right for those tiny spaces. Set up a delay command to put things back to normal such as deleting the enemy and putting the player where the enemy was. You can use commands to control enemies to cause the enemy to go in the right direction by checking the players face direction. Hope this helps!
