haha that's so much fun! As any jam game, it needs some balancing. Here are my suggestions on this subject.
- I ended up only using the wall to quickly surrouding the wolf the second it appeared. I never really care about the rest of the items.
- The wolf eat too quick in order to make other strategies (IMO).
- If the wolf was a bit slower, and you weren't able to build after the wolf showed up, you'd be forced to think ahead and build "defenses" before the wolf shows. Something like that might allow you to add a bit more strategy to each level.
It's really a very solid entry, congrats! :D
