Well. I see you have a 007 soundtrack there! The game was nice. I sugest you do more work (i´m sooo exausted of writing reviews, but it hink this will help). Make a reloading mecanic., with bullet limits, please. Try to make the targets fall when shot on, and also a cover mecanic, so later in the game the targets shoot you, and you get to cover. And give a little challenge, put different weapons, like, start with a pistol (can be infinit bulllets), then a uzi, then a shotgun, then a AK-47, and so on. Try to make different levels too. So, that was a simple review, but I hope its helps :)
