Raft Survival Diary is a casual game where you start on a small wooden plank in the middle of the ocean. Your main goal is to collect drifting wood from the sea, either by gathering floating logs or harvesting trees that grow on your raft. As you expand your raft, you can also rescue survivors you come across on the water—they will join you and help speed up construction. Gradually, you will improve and enlarge your raft, explore new areas, meet new companions, and continue your adventure across the vast ocean.
