Maybe try something where you are on a island and you have the find a secret treasure and your the last person out of your family that came pack from the treasure finding. So you end up heading out to the island with some supplies to survive like food, plants and animals and also tools and armor. Soon you start following you family's tracks towards the treasure and you have to go through many traps and puzzles until you get there. When you arrive all you find is a small golden room with the treasure in a vault across from you. As you head towards the vault you there is another vault with your family in it. You then get your family our, take the treasure and leave... But you still wonder how they survived in that cage for all of those years...
I hope this is what your looking for!
