Ogrotron is a fast-paced arcade game for Java phones in which you need to collect all the fruit and destroy the ghosts.
It might sound a bit like Pac-Man, but Ogrotron is actually a pretty unique game. You control a white robot who you move around the screen using the directional buttons or keypad keys. The robot fires laser beams out of the front and back, and you need to kill ghosts with these.
The gameplay in Ogrotron gets very frantic as you spend your time dodging the maniacal ghosts and collect all the fruit on the screen. Once you've cleared the screen you can move to the next level. This is more difficult than you might think because Ogrotron is very fast.
Graphically, Ogrotron is pretty poor, and its visuals belong in the pre-8-bit era of video gaming. The garish background color schemes often make it difficult to see what's happening on screen too.
If you can see your way past the psychedelic visuals then you'll find Ogrotron to be an addictive, high-speed arcade game.
