Raft.io

Game description:

This is an io version of the famous Raft game. Here you will be thrown into the middle of the sea with nothing but a little raft at your disposal. You'll have to painstakingly build it into a big and comfortable vessel adding boards to it that float past. There are also other materials in the game from which you can create all kinds of tools and weapons. Don't forget that your character needs to eat and drink otherwise your trip won't last long!
