Explosive, projectilally...
Killing a square with it's own green lasers, and then screaming PWNT! at the top of your lungs? NEVER BEEN MORE FUN. Addictive, Add more upgrades, Maybe a gravity field one, or even the ability to go bullet-invisible, making bullets pass through you, once in a while... Powerups for V2, anyone?
10/10 and a 5 rating. Keep it up, yet another innovation to Newgrounds.
