Just a simple time-waster game. Some minimal resource management like catching fish, collecting water, and collecting logs for a raft. Goal is to get off the island as quickly as you can in 30 turns/days. There's also a survival mode. Survival mode works a little bit different where you try to last as long as you can on the island.
