If you didn't know already, that is a lot of levels for an engine called "BlitzSonic", made by Damizean.
He stopped making it because of morons ruining it and soiling its name by adding recolor characters and and making useless crap.
I said stopped, which means it's not finished. Which means, last time I checked, no end sign posts, no actual gimmicks, and nothing more than an engine. What this guy here did, in that video, was perpetuate the agonizing "living-dead" state that BlitzSonic is in: Damizean released the source code, if my mind doesn't fail me. Why has NOBODY done anything else than add terrible levels and bad character models to it, instead of trying to actually make a game?
What I'm getting at, is; That is not a game. Enjoy your featureless running around.
