Uploaded my game. I didn't get done everything I wanted to get done, and the gameplay isn't as fun as I was hoping, but for five or six evenings I had a blast, learned a bunch of new stuff and remembered a bunch of stuff I'd forgotten. First game jam, first game. Wish I'd started on Day 1! I feel like I got the main mechanics 70% there, but with an extra three days I could have (1) added a bit more polish, (2) added more Blender assets, and (3) made multiple levels. But still, I'm happy! Maybe I'll work on it a bit more.
If anyone fancies giving it a try, you start off controlling one zombie, but you can bite people onto your team. Convert as many as you can and stop them escaping on the rescue helicoptor.
