Johnny's Island is just a simple time-waster type game. Some minimal resource management like catching fish, collecting water, and collecting logs for a raft. The 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. The style of gameplay is loosely based off an old C64 game called Island Rescue and the visuals are reminiscent of an old windows screensaver called Johnny Castaway.
