Very fun game with simple controls and lots of ways to customize. Berzerk Studio always makes cool games and this one is as well. It's easy to pick up and play and has a scheme to keep you playing over and over. For all those complaining about the pay to play aspect... then don't pay. No one's making you. You can still play and if you try hard enough, still do quite well. You're right though... how dare they put time, energy, and money into a game and then ask for a donation. You're absolutely right. All these guys should just make flash games for your amusement. Maybe they're doing this for a living? Not everyone on Newgrounds is a solitary guy doing it strictly for the fun of it. Grow up.
