There is a big reason why it is called RRRRRRRRRRRRRRRR.
This game has a nice idea to it. It's a game that seems nice and normal then it is just boom!! Enemies everywhere firing at you while you inevitably die due to a wave of bullets. Honestly I think it was really good. I especially like the great challenge while trying to survive while dodging infinitely while shooting enemy's as they duplicate in numbers every time you kill one just so you can get a highscore. The game is very simple, but I enjoyed it. My only complaint is the fact it gets really laggy when you get farther in the game. Otherwise I give this a 4.5 out of 5 stars. A good basic and simple game.
Nice job :D
