Rototo

Tap to rotate your shield, stopping incoming hostiles in their tracks. Whether you're lounging on the sofa or riding the bus home from work, you can always compete with your friends for the highest score in this retro-styled arcade game.

Rototo is a space survival game where you have to fend off enemies and their projectiles to preserve your core. A rotating shield is the only thing standing between the alien horde and your inevitable destruction.
