Different from the usual but fails to be entertain
You cant do horror movies with sprites mate. Not to mention the song wasnt creepy it just detracted from the experince. The deaths were predictable, For some reason i seriously doubt that anyone....except maybe Sonic.....would rush Eggman the way Knuckles did but i dont see how Eggman could capture sonic like that. But your animation was fluid and it shows that you have quite a bit of flash work. Work on your sound a bit and remember originality is good but good ideas require good writing just as well.
