4 stars: The game is not bad, in the beginning, it tells you how to do it, then once you get the drill it gets slightly boring, even though it's kinda boring, the controls aren't bad and the gun shots are smooth, rarely any ads and you might glitch a lil bit, otherwise not bad
3 stars: Really an ok game. My highest praise is that the advertisements you see for this game are literal representations of actual gameplay. The ads are very reasonable in frequency and duration, and are not required. Aiming is not sensitive enough, and the levels are not very difficult. Gameplay becomes monotonous; your gun starts to look exactly the same each level. Worth playing but only for a couple of hours.
