I really enjoy this game. The Difficulty is just right. Guns are fun to use and pretty balanced.The furthest I've gotten so far is level six. One thing though, when you're in the game and you pause, there's a button to start the game. I clicked that the first time because I thought that'd resume the game.You might wanna change that so it resumes the game instead of restarting it. You also might wanna add a save feature.
