Here are my thoughts:
Ideas:
- Being able to fancy things up after time would be nice. For example the water purifier, it could be used as it is in the beginning of the game, but with time it would be nice to be able to build a better looking or even semi or fully automated water filtering system/device with more materials and/or more complex materials.
- As many people already suggested, more and also usable furniture would make the raft more personalised and would generally help getting more out of the game.
- I would suggest being able to craft a backpack of some sort, so one is able to carry more items.
- I think it would be fun to be able to dive just a little by putting oneself on a rope attached to the raft or so. This could be used as a way to implement new materials in the game like stone, sand, shells, corals and generally stuff that can be found in the ocean. I think it should be a limited option though. If one would be able to dive very deep or too far away from the raft, it would take away the game from the general idea from surviving on a raft, which I really enjoy,
- Having different wheather from time to time would be a nice touch. Rain could force the player to build their grill and water purifier under a roof and seeing higher waves instead of the always flat water could add more diversity.
- It's nice to have a shark buddy around so one doesn't feel too alone on the ocean, however, one could add more animals. Maybe birds in the sky (maybe shootable with a crafted bow) or dolphins who can be seen jumping out of the water from time to time.
- Being able to catch fish with a net
- It always looks like the raft is on a fixed point in the ocean and the incoming stuff is floating by without the raft itself moving across the ocean, I think it would be nice seeing the raft moving as well.
Bug fixes:
- When your raft is big enough the shark sometimes swims in circles and swims through your raft. Not attacking it but unnaturally swimming through the wood.
- The shark can put his head through your walls in order to attack your foundations of the raft, which seems kinda pointless.
- I wonder why repairing something takes more wood than the original building process.
