awesome!!!
I loved it! except for one thing, it was too much like "defend your castle" except with different guns, I loved the guns, expecially the slow-reloading antigravity gun, but it went into effect too slow, and you should've had a rocket launcher.
But anyway, what's up with the "if you buy too many gunmen they game plays itself" effect? It got soooooooooo boring after i got 150 gunmen and just sat through levels trying out my gravity gun, which came into effect too late as the units i tried sucking are already killed by the huge numbers of gunmen.
i hope you make a sequel, but add more weapons and more upgrades, and make it less boring. oh yea, MORE TYPES OF ENEMIES
