its ok, the difficulty on the levels didnt really progress (more of "heres a hard one, now heres an easy one"), half of the levels were just red things blinking on and off in the same order over and over, stop and go, stop and go
overall though, not a bad game (3/5)
this game is an old version which is really alme, there are so many glitches with this version (50/40 levels, money per enemy isnt displayed, right menu looks blurred and hard to read, etc.)
come on lol, update it with the new version atleast
bug glitch near level 6 or 7 (cant remember which). They just keep coming and coming and coming past the goal (I killed over 900 of em on that level where there are 10 at a time
this game is very difficult to beat...Im sure I'll complete it by later tonight
very addicting though! I like the art direction with this game and the gameplay is simplistic but catchy!
