I played one level and noticed a lot of problems I then lost on the next level to see what you did for an game over screen. The gravity in this game on the arrows is too strong, it barely reaches halfway through the screen. It takes to many shots to kill the soldiers with sheild. You have to restart the game to play after you lose. The graphics are way to minimized. upgrades cost too much in comparison to how many you can get, plus you have to use upgrade points to repair. Blimps are overpowered as well. This is an overused concept as well. If you can fix all those problems and add something unique you might have a decent game.
