To be honest, I feel that this game has a lot of potential, but it is quite obviously too simple. One gun, one melee attack, some upgrades, and a whole lotta enemies. If this game had some additional content added, it could definitely be a 4/5 star game. However, this is still a long way down the road. The game is much too linear and repetitive, enemies only get melee weapons, and their attack animations don't correspond with when they hit you. (damage is dealt as soon as the enemy attack animation starts) Graphics/art is ok, if a bit glitchy in animation. And although i can appreciate the good old A/S button attacks, the "click to move" aspect of the game should definitely be subject to change. Can't tell you how many times i died from accidentally clicking on an area by mistake. Fix that stuff up, and you should be good to go.
