This is pretty bad.
I mean honestly - there's barely any gameplay, you can't even move, and you have to shoot before your character will aim that way. The graphics could really be better. There's no penalty for just standing still and getting shot at (except for a low score on the leaderboards). The author's attempt to add a story to the game is stupid and makes the game even worse. It wasn't very fun, but not no fun at all. 2/5, 4/10.
Also, stop giving this high ratings because you got on the leaderboards, honestly.
