This was a pretty cool game. The graphics are crisp wen well-made, music matches the pace of the gameplay, the controls are easy, riding on the pig's good fund and killing aliens is an effective challenge. And there's plenty of upgrading and evolving to do. I like the idea of growing ammo too, but in the long run it just becomes tedious. Wouldn't it be easier to have the aliens drop ammo, or drop coins that could be used to buy ammo? A common approach sure, but it's effective. Otherwise it's a great game, keep it going!
