This is a good game, it's interesting to play. But why do you take damage on contact with the enemies, they already attack by shooting, it's just annoying when you accidentally touch an enemy and die because they decided to shoot at the same time you hit them. Another bad thing is that the enemy's damage scales too high in the late game so you always die in one hit. All the other features are amazing, though the pistol is weak. The balancing is fine, the gameplay is fun and it just feels good to get a highscore.
