My first flash game I have ever made. It's a basic platformer game, with the levels slowly getting better, with Sonic characters. Shift to jump.
NOTE: It's my first flash game, as it's super glitchy and buggy. If you come across a platform to high to jump onto, try to glitch out the platform to jump onto it. By that, I mean try to jump on the side of the platform, you should stick onto it, and then try to jump on top of it. I've tried that, and it works. :P
