An old game on cartoonnetwork.com?

Alright, I can remember an old game on cartoonnetwork.com but can't remember what it's called. It was a very dark game and was extremely long. I can evan specifically remember it saying"warning this game is extremely long" i think it was even divided into multiple parts. It took place in a spaceship and you were this weird robot. Can anybody give me any ideas on what this game was called?
