gameplay ruined...
I liked the idea. It would be a good way to kill an afternoon if it were perfected. First, the time needs to be removed. The time goes slow at times, and fast at others. Next, there needs to be more levels. Next, you need a continue point. But, that would require removing time. I did not enjoy making it to level thirteen and then running out of time. Next, The initial infect gas needs some perfecting. I hit a span (completely maxed out the upgrad for it as well) of about 10 people in one area, and only two got infected. Not even close to fair... Anyway, fix it up, and it would be a great way to kill an afternoon.
