@Peknanjo That actually isn't the game doing that to you. It's probably a slow internet problem or they way your computer is handling games. I would look into those to see if you have an issue.
What I don't like is you put the collision box to far from the virus. So when bullets come they hit you when they haven't even touched the virus. Should be fixed :/
@eroge11, That's actually a pretty nice idea.. But once you get to a high enough level, and having a pretty decent base, wild monsters don't put much of a dent.
I didn't code at all. O.o
