If you're bored and fancy giving yourself the willies to liven things up a bit then install Zombie Mansion on your phone.
This Java-based game charges you with the tricky task of escaping from a huge monster-infested house. In order to do this you need to collect all of the crystals on each level, and pass through the trapdoor to the level above. As well as dodging zombies, you also need to beware of other obstacles such as spikes and acid pools.
It has to be said that Zombie Mansion is terrific fun, and has all the charm and character of those classic 80s ladder-climbing adventure games like Pitfall, Donkey Kong, and Jumpman. The graphics are tiny and the game characters are low on pixels, but it doesn't affect the gameplay, which is highly addictive.
The controls in Zombie Mansion are very straightforward - you use the directional pad or the 2, 4, 6 and 8 keys to move your man, and press the center button, or 5 key, to jump. Succeeding in the game is another story though, and Zombie Mansion is a very tough challenge that requires both skill and logic, so it will test all your gaming powers.
It might not be as scary as Resident Evil, but Zombie Mansion is great retro-style fun.
