Bacteria - Arcade Edition
From Ouya Wiki
Bacteria starts off slowly, but by wave 4 the game is frantic, lots of chaotic action that keeps you on your toes.
Inspired by multiple classic arcade games, the basic idea is to stop multiple waves of enemy bacteria from snatching away your last few remaining cells that are located in the center of the screen.
However, there are also some bacteria who are intent on destroying you - so you must destroy them first. If you succeed in lasting 60 seconds then you will be rewarded with a further cell to protect on the next wave, and so on...
