Here’s an interesting game called Cell, where your job is to consume the other cells. It’s a little bit harder than chasing as each time you propel your cell, it loses mass. You can only eat other cells that have smaller mass than you otherwise they eat you. But eating other cells makes your cell bigger. You can also change the speed by fast forwarding or putting time on slow motion, as well as pinch and zoom to view the whole map or close up to make more refined movements.
Price: Free or £1.29
2.0 Studios brings you Cell, a touch based cellular life game, where your goal is to grow into the biggest cell. Use a clever mix of cautious thinking and twitch reflexes to eject your cell’s mass to propel you through each level, whilst carefully conserving your mass.
Absorb your way through 3 different game modes with 15 levels each for a total of 45 levels that will entertain and challenge you from start to end with gravity wells, intelligent cells and much more.
