Maybe you can add some magical stuff? Means some potions, a magic wand or portals or stuff like that? :D
Would be really cool!
You are right. It has nothing to do with surviving. But I think its kind of boring to use the "normal" stuff to survive every time. You don't know why you are on this raft. Maybe you live in another year where you have cool techology? For example a machine that generates a portal? Why has everything to be logical? If you don't like it, maybe they can add this to a special event.
