If you're looking for a great free iPhone or iPad game to download, be sure to check out Rhythm Rocket. It's a new rhythm-based title that takes advantage of your device's music library.
In Rhythm Rocket, you take control of a small spacecraft, and attempt to navigate it upwards through obstacle-filled levels that are created from your favourite songs or the game's four in-built tracks.
The speed of the game is influenced by the songs you choose. So, if you pick 'Worker's Song' by American punk band Dropkick Murphys, don't expect a walk in the park.
Rhythm Rocket is packed full of "unique leaderboards for every song", so you can compete against the rest of world.
