Joe Danger is all about the weird and wonderful levels that can not only be played, but also created. Creating levels is almost as fast and fun as playing the game itself; as you ride through your level, you can select Edit at any time to freeze the world and play about with it however you want. You can drop a ramp then launch Joe over it, or place a shark tank in there just for good measure.
There are no objectives, except to create the most impressive, ridiculous, record breaking stunts you can think of. Create a canyon of doom and try to break the world record for most broken bones, attempt the largest loop-the-loop chain followed by a pile of mousetraps or design an assault course laid out like your bedroom floor.
You can even create your own challenges to send to your friends. Lay down the gauntlet with your own multiplayer race level, setting out a Coin Dash against the clock or a tricky Target Smash. Compete for high scores or even just for the most dangerous creation, and see who has the most guts.
