I made the music in this, so I'd appreciate if you could go on my soundcloud account and check out some of my stuff ^_^ https://soundcloud.com/jolelolel arrow keys to move, press z to jump. press down while running to roll. press z while ducking do a spin charge. (you have to keep on pressing 'z' like in the old games. Pressing it once and holding it won't get you very far!) run into the bouncers to bounce :P This isn't actually the latest version, but it's probably the most fun to play as it is.
It's a simple sprite swap, and did a few more things. May make more of these "hacks" in the future. They're quite fun to make. Animations for certain things may be sorta wacky, but do understand that there are not the same animations for Eggman that Sonic possesses. Keep in mind that Eggman was never playable usually. Besides the goofy animations, here is something that no one has done before! Enjoy!
