Add fuel for cooking stations and water purifiers. You can use thatch (3 seconds) planks (30 seconds) or rope (6 seconds). Also, make it so your raft go over oil spills. You can use tin can to fill up with oil. Also, and cauldrons as an alternative to water purifier. This will be a big cauldron, I'm thinking 1/2m x 1/2m base x 1meter height. It takes 8 tin cans to fill but cooks all at same time. Therefore, I don't have to make 8 different tin cans. Loving the game bwt!
