A game idea made by Philip Dorrel, we (well mostly Dayne) have created a portable version of his idea for the PSP called Prime Shooter Portable. What is it? It's a flash game where you shoot down blocks of numbers using prime factors until it's a prime number then shoot it with a speical "P" which destorys the block. You can also destory the block by having a division that equals to 1 ( 2 ÷ 2).  This game is pretty fun, even though it sounds like math (which it is). It's like playing a stragetic game of Space Invaders.

It may sound like it takes a lot of math, but it's easy and pretty addictive.
