Errr..... I think I broke your game.
Not only did the game progress slow, I was able to build a armory, buy weapons from it and then restart the level, retaining the weapon. Didn't matter though, seeing as the only functional weapons were the flamer and the machine gun, along with the starter pistol.
It's Alright
It's clear that effort was put into this game, but I just find it hard myself to get into. It may just be my taste, or it could be the game itself. I don't know.
Too Laggy
Okay game, but I can't stand the lag.
I'll come back once I can lower the quality.
Quality controls?
Needs quality controls.
Fun but glitchy.
This was a very fun game, what with the turret building and storyline, but at later levels it will glitch badly (Screen will freeze if you move from one computer to another). I'd still recommend this game to other gamers, but I'd take a look and try to resolve some of these glitches if I were the programmer :)
