Mechanically it doesn't differ much from the usual knives games, I mean even in the 50 games in 50 hours challenge or what was it, it's the guy who made the snail vs AI game, that predict your movements, but I digress, in his challenge he made it into truly 3D, which is instead of circle, it's a sphere, all I want to say is that there isn't much a twist mechanically.
Cool game, it pretty fun
