sonic the hedgehog

I need help finding this Sonic Flash game. I remember there being a bitter sweet anime like opening with some sort of music. It looks like the sun is rising or setting and Sonic is doing something (I can't really remember.) And when you start the game it acts kinda like a dungeon in the original...

I love Sonic the Hedgehog, a sentence I’m sure will trigger many a reader’s fight or flight response. But I do love Sonic the Hedgehog. Not the movie, it’s okay. Not the character, I’m unsure how to feel about him. Not the franchise, I’m even less sure how to feel about that. Not the 2006 game...
