Needs work
While I like the idea of the game. This needs A LOT of work. First off, the targeting system is too slow for the speed your chopper is moving. While this may have been the idea to make it more challenging to shoot targets. It doesn't help when you can still shoot targets that have made it past the front of your barrel. The upgrades are too cheap and easy to afford. But they still don't provide the damage you need to kill the right zombies. I spent so much time on one of the tougher zombies that I passed up several weaker ones I could have just killed instead to reach my target goal. Third, the music is cheap and gets easily annoying since it's a 5 second loop of the same thing. Overall, good idea, just not put together the best or given much work into it. Upgrade or possibly make a better sequel.
