Plan Game Scene

My plan game scene is going to be about social studies.What I'm goign to hide is going to e pirate stuff.It's like the stuff that the pirates use for traveling.Like for example the food,water,ship,and other cool stuff.When the objects are hidding the pirates are going t be looking for them.My backround is going to be a island or in the ocean.But in the ocean all the items are going to be floating,instead floating.There is going to be like 12 or 15 pirates.All the pirates including the boss are going to be looking everywhere.If you find all the items you are going to win,and if you find half you lose.I'm thinking abot putting a timeSo that is what I'm going to do for  my game scene.
