Good game.
This game concept is realistic in the part where the character is shown building the turrents and somewhat taking part in the action even though it is just running away from enemies and planting mines,instead of the charcter being stationary and the turrents just automatically set up themselves.The animation is quite well done,the gameplay is fairly smooth and there are various typesof enemies to fight with,so keep this up.However,the game will be better if there are upgrades included in between each level for the turrents(firepower and more turrents) and the character(weapons and skills) and maybe if the sound effects are more realistic like the aliens exploding like bombs.
