Press the Green Flag twice. Use the arrow keys to speed up or slow down (essentially left and right movement) Use space to jump. When an alert (!) is purple or yellow, a badnik is approaching. You can defeat them by jumping. Just don't touch them when you're not in a ball. When an alert is black, spikes are approaching. No matter what, you will get hurt by them, ball form or no ball form. Ring monitors will give you 10 rings. If you get hit without rings, you die.
I love it when I put a lot of work into a project and it gets no views. Well, this game was on the backburner for a while. Sonic Mach Speed is a game where you control Sonic, although there is a twist. Sonic now runs no matter what, you can only control his speed. Of course, you can jump as well. Sonic collects rings and encounters Dr. Robotnik's evil badniks along the way. The more badniks you smash and the more rings you collect can affect your overall score and rank. Test your reflexes with Sonic The Hedgehog: Mach Speed! Programming by me, lukeekelly. Sonic sprites from @sonic74, @Sonic2HD, @Misterythefox13, and facundogomez on DeviantArt. Other sprites are from The Spriter's Resource. Notes: Sequels will come out soon, with higher difficulty and starring Tails & Knuckles. There is a glitch where 2 ring monitors can come at you, and I don't know what causes it. If someone figures out the cause, please tell me.
