Play a Sonic, while you go between sane and insane. Try to help him by switching as his friends Tails, Knuckles, Amy, Rouge, and Cream and her her chao: cheese and Shadow: his rival.
You start as Sonic and meet his other three, if you play the game right. They can kick you right back to the beginning so be careful what you pick.
Its LIFE OR DeAtH, you have 5 weeks to help Sonic gain control of his mind or just kill him in the end.
You will have 1-3 choices of what to do, pick right and you'll live, pick wrong: well... They don't want me to tell. HAVE FUN, BE SAFE, and STAY Alive!
There's only two endings: the DeAtH and and HIS LIFE. The difference: whether you have an epilougue.
