I’m thinking a larger variety of doors, like a sandstone or stone door. Also, if you spawn in a desert, Palm trees don’t give you branches, and if you can’t find seaweed, then you can’t make a raft to leave the island.
My main suggestion is that we should have barrels of materials (variety) that store water, filtered or not. Also, a container that would take longer to purify, but you can drink out of it two times (It’d be able to hold maybe…2 drinks, so you would have to gather two ‘drinks’ before stilling it).
Also, some way to make raft ‘floors’, so you could build on sea, maybe gather oil for fuel.
