Arrow Keys to Move Space to switch gravity. Down arrow to Jump Upside Down. Get to the end of the screen to go to the next level. Wall Jumping only works on the Ground.
Gravity-Switch Platformer ... With a twist! This could lead to some pretty interesting platformers. This is, just like the original, a base, but I have included a couple of testing levels to demonstrate some possibilities. Sorry about the glitches. Also, to Platformer123, I apologize for changing the sprite, but there were two pixels in the original sprite which I could not find so I had to remake the costume.
