If you want to take an advise, do not pay attention to people criticising too much. This game is really good. 4.5 at least. Such good work for free. The control may take a bunch of minutes to be mastered (shooting to the low corner is just after the movement pad) but I thank to the people who make things like this possible.
Terrible Lousy controls not user friendly, bullets pass through targets, line of fire an epic fail. This is a con app designed to make you buy coins but even if you fall for it you will still loose!!!!!!!
Has potential but needs polish. Though the 'barrier defence' gameplay is fairly simple, the variety of aliens and weapons, the solid weapon upgrade system, the armor customisation options and appealing comic-style artwork make this game quite addictive. However there are quite a few glitches or weird design choices that currently spoil things a bit. While the weapon sounds are decent, they are spoiled by a weird beeping/screeching sound when shooting; also moving produces a constant rumbling sound which has got to be a glitch. Other annoyances include weapons sometimes getting stuck firing so they overheat, occasionally being unable to shoot even if weapons aren't overheated and sometimes being unable to target aliens right at the bottom of the screen. Once all the glitches etc are sorted out though, this could be a pretty nice game.
Horrible Mechanics are all jacked up. Certain places you cannot aim if monsters get too close. Uninstalled
Good time waster It is really fun and challenging at times, but every once and a while it will kick me out but it rarely does it.
