The crash is not uncommon in the ocean and our hero in the game Rubber Dinghy did not escape this sad fate. He was relatively lucky because he survived, was on land and he had a rubber lifeboat in his possession. While it can not be used, the boat is leaky, the island is very small, but if you look, you can find very useful items here. A broken bridge can be repaired, there is enough wood on the island, fight with crabs, it will bear fruit. Collect all the objects that you will find, they will definitely find use and the poor fellow can leave the deserted island to return to the big land. Be smart and turn on the logical thinking from any situation there is an exit.
