Barring the excellent return to form of Sonic Rush, SEGA have had troubles recapturing what made Sonic the Hedgehog such a great platformer. It's hard to shake the feeling that Team Phobic have cracked an element of what made Sonic so good and have distilled it in to their latest game Bounce On 2: Drallo's Demise.

There are two basic movement controls with the default being tilt based, but for those who are more comfortable with virtual pads buttons are also available. The level of control is surprisingly good, with complex jumping maneuvers being easy to pull off with either control system. The gameplay will be familiar to anyone who has ever played a platformer, but added features like skill-based jumps give the game a modern edge. Keys will need to be collected based on challenges in order to unlock later levels, much like Super Mario 64.

Bounce On 2 goes for a modern 16 bit feel with 2.5D graphics. The textures are smooth and hand-drawn, but the transparencies don't always blend in well with each other. In game 3D models add depth and help to show the physics being used more clearly. The music is atmospheric, but not quite as interesting as the somewhat cute exclamations and sound effects used.

From the gameplay to the graphics, Bounce On 2 at some deep level carries the true game genetics of what made Sonic so much fun the first time around. For most old-school gamers there might not be enough that's new to keep you enticed, but the great gameplay and responsive controls make it a worthy platformer for anyone's iPhone.
