Arrow Keys to Move, and Up to Jump.
@griffpatch for the tutorial and second fix in this series. - Changelog - 12/9/2021 - Made the Vanishing and Fake walls more legit by adding the outline code to them and removing their outlines in the sprites 11/22/2021 - Added an hidden item along side a new "Fake Wall", and I also renamed the other wall with the blue key to "Vanishing Wall". You need to use the fake wall to get to the hidden item.
