That's a nice idea on replayability! But it can turn into a negative loop, making every run harder if you don't regrow the environment quickly. Tricky, but still a good suggestion.
Wolves were made as an inevitable danger on purpose. I thought about taunting them with food or stuff, about an end game where you, e.g., find a flare launcher (I guess that's how it is called?) to be saved, but unfortunately I didn't came up on how to add this end game without making replays extra short once you find out how to do it. Maybe next time!
