Different Language Required Especially Turkish, Russian, Chinese, Japanese, French, German But Absolute Turkish

Planting trees requires soil

You could get soil bags from floating barrels.

I've got some suggestions. So;

How about doors? There could be a door with a window and just a regular door.

There could be birds flying around the ocean, and the player could hunt them, tame them or just simply let them be. The taming would be giving them food, (food as seeds) and maybe helping them.

New weapons, like arrows, you could make a bow or just throw them around (the bow would make more damage but take longer to charge).

Bananas, apples and different berries. Edible and non-edible flowers would be nice too.

Different fish and sharks.

Difficulty levels, they would define how many sharks there are at a time, how much recourses would pass by and how quickly the player would become hungry and thirsty.

Multiplayer. We need multiplayer.

Make the raft look like it's moving more, there could also be a way to lock yourself to one place.

Day-night cycle, seasons and weather.

A way to make stronger rope and put it on the planks. It could be just decorative, or it could be used to tie two areas of the raft together. If it was just flowing in the water with no purpose, the shark could hang onto it and rip the plank it was connected to off.

The more the player would build things, the better they would get. If the player is good at building and has the necessary recourses, they could make some really cool even automated stuff. The systems would not be the best, and the player would still need to get fuel, so it wouldn't become boring.

There could be a gamemode where the player would need to stay alive in extreme situations for a certain amount of time before they get rescued.

A backstory. Why is the player on the raft?

Also, sorry if I made any typos, English is not my native language, forgive me.

Day & Night cycles and possibly weather might be cool. There'd also need to be a source of light such as a fire or torch.

There could be a way to get stone (very rare, though) and build a furnace / refinery where 10 scrap metal can be turned into refined metal, and used to create reinforced foundations.

If islands were to be implemented, I would also like to see shipwrecks.

Add multiplayer to the game.

Add other creatures then sharks.. like The kraken(big squid like monster) or different types of sharks with different damages.

A level system would be nice to have.. different levels unlocks new crafting stuff.

This game is really fun to play... keep up the good work Raft Team :)

Add some type of chest

You can do on multiplayer mode survivor.

The players will have their own raft for each and they will swim with them, raid with them, and survive with them.
