MumboJumbo has recently released a "completely revamped" version of retro-styled shooter Luxor Evolved for the iPhone and iPad.
The game tasks you with firing coloured orbs at a string of moving spheres in order to match three or more similarly coloured balls and remove them from the field of play before they reach their target.
You have to do this across more than 60 levels, secret levels, and bonus levels, using no fewer than 20 helpful power-ups. These give you the ability to - among other things - launch fireballs, slow time, and summon a meteor storm.
There are four different game modes to delve into, as well as 33 Game Center achievements to unlock.
Luxor Evolved is available on the App Store as a Universal app for £4.99 / $6.99.
