Victory!
I really enjoy defense games, and this one is great.
the weapons are varied, and fufill multiple roles (not redundant), and have cool effects. The sound effects were also good, especially the moans, and overall a great job.
there are a few things I'd like to see in a sequel:
-fix the weapons glitch (if you buy an upgraded weapon, then you can't buy the earlier versions)
-more upgrades and weapons (i got them all pretty fast after getting overkill)
-EXPLOSIVES! they're great for every game and would be exceptionally useful for zombie crowds.
Again; nice job, great game, please make a sequel.
