Legit really fun. At one point I found that with a good shot I could skip some people but it turned out you have to kill everyone. If it was about getting to the end instead it would bring a lot of open endedness. Please keep this going.
Thank you for playing and the feedback, I considered the idea of having a specific host that the player must infect and that would be the end of the level but eventually decided against it, you bring up a great point though that it would allow for more varied gameplay so I'll experiment with it!
