good game. it got really laggy once u get the gatling gun, after lvl 20. for the 2nd one u should make the bullet shells disappear instead of them pilling up on the ground, they also lagged it up a bit. overall its a good game. i give it a 4/5. u should definatly get some badges for this. i hope the second one is even better!
...btw there are 34 levels for all of those who are wondering.
p.s. the gatling gun should cost more than the chainsaw. and u should give the gatling a heat gauge that has to cool down after a while. also, clips for the guns would be nice and a reload button. good job. :)
