1. speargun (faster way to kill shark)
2. add multiplayer( mainly because this game is awesome and i wanna show it to my friends as a group)
3. add like metal flooring/foundations/walls
4. some type of base defensive spikes or like buoys (that we can assemble and cast to get the sharks attention away from the base for a short time)
5. some kind of back story as to why we are stranded or how it happened
6. cast able nets that allow us to catch more fish or larger fish(cuz i like the fishing aspect in the game its epic)
7. cabinets as an alternative look to chests
8. an automatic water filtration system(sorta like it gathers water purifies it and makes it drinkable)(like a later game craftable thing)
9. a larger furnace(like how a real grill works or something so we can cook more food in one instead of having to have several grills)
10. sea birds that ocasionally we can capture for eggs or meat(or keep as a pet)
