I have some ideas.
Add: beds (would be made with wood nail and sheets) Add another basic need like: energy (it would be recovered while sleeping in bed)
Add: multiplayer mode (which would connect two computers) Add more types of trees with their food, such as apple, guava, banana (which would be planted where the coconut is planted and would be achieved in the same way that we get coconut in the game)
Add more food to be planted like carrots, wheat to make bread, melancholy, pumpkin ... (that would be planted where the potatoes are planted in the game and also obtained in the same way)
Add: islands by the sea (in them they would contain trees and plants could also contain terrestrial animals in the islands)
Add: boats with capacity to hold chest (which would be used to reach the islands)
Well these were some ideas that I had to improve your game I hope you like <3
