nice game, although i dont think the upgrade's are that balanced, i tried first with buildings etc.. and than with bullet damage upgraded, it worked out best the second time. Just finished the first epic battle so i may be wrong (bullet damage to the max)
lvl 18, you need bigger numbers, maybe as powerups ? possibly a '/2' power up or combo points, and you need something that lets you go down again when you make mistake's
well done, only i got a bug when restarting a lvl, a machine gun in stock was still there, so i could start with extra cash, also the gun on top on campain 4 was hovering in the air, not able to shoot or get hit by falling bombs. Nice game though, i used the machine gun till i could use the plasma weapons, witch all shoot at the same time, with a normal cannon gun with his health maxed up as a tank. worked perfectly (almost). 4/5 cause of the bugs
verry good game, only one frustrating point, lvl 3 ... i had no control
for lvl 2 just move the mouse slowly over the mass of collors, its easy'er to keep them away from each other that way
put the game on easy, buy the shotgun, than the mac (better than the assault rifle) and than save up for the minigun use, die from some pipe bombs at 21 and youhave the badge
