For quit buttons, they are slightly counterproductive in terms of player retention. You don't really want players to quit your game, you want them to keep playing!
Your treasure is in the same spot so after beating the game once, there's no incentive to play again. I like the navigation stuff but there's more you could do with it. The art and sound effects are completely unrelated to the game, which makes the overall direction whacky and odd. Why should I find the treasure anyway? I can't do anything with it once I find it. What ideas are you trying to prove/disprove with this game concept?
