All this is just a quick tech demo lol. I might add more content like circles and such. Press "Left" or "Right" arrow keys to make the blue square move 4 pixels a second either direction. "Space" lets the player jump.
Something I'm working on out of a challenge to make a platformer out of a single sprite. Not sure why but fullscreening breaks the collision. Please play out of fullscreen and refresh the page if collision doesn't work!
