Earth Shaker is a puzzle game that was originally released for the ZX Spectrum in 1990, and was written by Michael Batty. Michael kindly gave us permission to release this version for the XBox 360, which contains all his original levels, graphics and music, and has been extended to incorporate a level designer and replay feature.

The idea of the game is to collect all the diamonds on each level and get to the door before the time runs out. There are many things to help and hinder you on the way, including boulders (don't get crushed!), fire (don't get burnt!), bubbles, teleports, jumping jelly beans, forcefields, elixirs, reversed gravity and much much more.

You can try a demo and purchase the game from the XBox 360 Dashboard, or here on the XBox website.
