Runs into some layering issues when there's too much in the surrounding environment, or in battle when you've got a massive inventory, and I once got a zombie encounter that had so many zombies they went off-screen. Aside from UI issues like that, I liked this one once I got the hang of it and I had fun gathering supplies from everything I came across, though it was a bit on the easy side (again, because I ended up having a ton of stuff in my inventory).
