It's terrible! I've had times where I am on the green bar still (75%), have turned around to the correct side and it just keeps going straight, as if it hadn't turned. Happens quite frequently.
Then not to mention simple lag. Only completed it almost, once... but used diamonds for it, which turned out to be just a waste of it.

It isn't "git gud" at it, it's not that. It actually has bloody issues.
