I really like the level design, models, and art - this was really well put together! The zombies were freaky enough to definitely want to keep them out, and when the lights came on it was satisfying to have a moment of relief. The tracking continuously went out while I was holding up boards to nail in and that amplified the anxiety of the experience.
It would be neat to have some sort of alternative "last ditch" action I could perform to keep the zombies out if I can't get a board up in time - I tried to nailgun a zombie in the head to no avail. Fun experience, thanks for sharing!
