I do realize this game is very early in development, so it may take some time for my ideas to be implemented into the game if they are found useful or interesting by the developers. I believe Raft should have a day and night cycle, a temperature aspect, beds, fire pits(warms the character and cooks food), more sharks, more weapons and metal bases. When it gets dark outside (night) the temperature could plummet and this would leave the character only two options, to light fire or to go inside of a walled-off room. To skip to day the character could sleep in his bed. Later in the game when the player has had time to make a base, more sharks will approach and attack the ship at once. The later on in the game, the more sharks. The next step is for the player to make metal foundations, wall, etc.. These foundations will not be easy to make and would require some farming. However, they would stand a good defense again the numerous sharks that will attack. To help defend furthermore the character would use his more advanced weapons like suppose a harpoon.
Thank you to the developers if they put some of my ideas into the game.
