It's hard to review, to be honest. The game is nothing new but it can be fun when you are lucky enough to play with other players and not just bots.
However the time trial mode is boring and repetitive. Don't even hope to manage to get two stars on most levels, you'll be lucky if you get one star because the timings are based on speed running and shortcuts, I'd imagine looking at the few youtube levels I could find.
As a multiplayer game it's worth playing. Not sure if it's worth the price considering how few players are online at any given time even after it was bundled just this month.
Most of the time I played was spent waiting for a match.
