Mabey if you had some houses(around 6) on the island and when it starts it randomly places something like 3 objects in 3 of the houses.
There should be a jail/cop place and a robber hangout
You can pick up the objects and and the robbers must get all in their hangout place while cops try and catch them or take away the objects
When the all the objects are in the robber hangout or all the robbers in jail the game ends
