Play to Learn Part 1

I learned that it best to camouflage the objects like in ''Dirty Water'' also to like put a hint button in my game because i want to make it it challenging but not to challenging that you cant find anything. Also to give information why is that related to the game like little fun facts.I also want to conclude the object list were you have to find the things that it says to find.I also want to put like something coming in the screen if you are taking to long to find something.
