J to toggle walls Space to fall added wall collisions but there is a huge bug when you activate the -y and +/-x collision blocks at once after double clipping above a small platform and then hold that key. it goes as far to the x direction as it can before it can upwards clip into an empty space before the upwards clip does happen where it immediately shoots you to a value that doesn't exist since the wall goes up to the ceiling. I also reworked when you fall but I can't figure out how to detect when you fall off a platform to initiate the falling without lagging out the project with a buggy collision block.
