Super cute! I love the art and sounds, the bonk is the best. Mechanically it holds up well. It maybe isn't particularly a horror game, but it's a fun little game nonetheless. One thing I would say is it would be nice to see how long each zombie has been waiting. I know after a bit the thing comes up to say that they're getting irritated, but when two zombies were asking for the same thing, it was easy to forget which got there first, and I'd give the food to the newer one and end up having to wait a sec for the other one to get mad so I could bonk him.
Wouldn't have been able to hear the sound without that though :)
