Something I would really like to see is the ability to eat food from inside the inventory by right-clicking it or something, that would be much easier than having to assign it to a toolbar then reassigning what was already there. Also, the ability to directly grow ferns (for thatch) in cropplots would be nice, instead of having to wait for palm trees to grow, or for some to float by. Another thing is maybe having to use wood/thatch for fuel in cooking stations, and perhaps being able to make more advanced meals that heal more food by using different types of raw ingredients. (E.g: Shark Meat x2 + Coconut = Shark Fin Soup)
So far this game is really fun to play, it's a great idea that instead of having to look for land you have to utilise what's in the ocean to begin with. Hope to see this game develop more in the future!
