This is a good mobile game. Or at least, it has the makings of one. The physics in it are great, mindless fun. A couple of things do kill the experience: the ads, and the randomness of the bullets. The ads are easy to get around, just use airplane mode, but if there was an ad after every, say, 5 levels, it would be better. The pistol from the beginning is the most fun gun, but, i did enjoy the lazer gun. If there was more of an emphasis on precision for later guns, this game would be perfect
