Neat idea, I like the urgency of gathering resources before a storm comes through.
Do resources respawn? I mined almost all of them the first day and couldn't do anything the other days.
They don't respawn, we discussed and decided to have a forced end of sorts. Otherwise it would be feasible to survive forever which would get pretty boring I think. In hindsight you can clear-cut the island way too fast so making it bigger so you have to venture further and further for resources would have made it work better.
