This games utterly boring once you get into the 200's (in terms of levels). Up till you get lazer gun theres practically nothing that makes you keep playing this game. Just uninstalled after beating level 477. The ad that got me into the game was alot more enjoyable than the actual game, which is suprising. Devs should consider releasing a new update with alot of content if they want people to actually keep playing this game. I may come back if they make the game more fun to play.
