Left and right arrow keys to move, space to jump. Don't touch the camera light (light gray area) or you'll be sent back to the beginning. Get the cupcake to advance! WARNING: If you have a condition triggered by flashing lights (like epilepsy), you may not want to play the game. The ending screen has lots of flashing. IF IT STARTS AT THE SECOND LEVEL (The "Prepare to Rage" level) just click the flag twice.
I made all backdrops and sprites. Platforming script from @Chronicle. 3/25/15: I added two new levels.
