What is that cheat box for?
I think the idea behind the game is cool, I have a few suggestions.
~Add a counter above the tree showing how many fruit that tree has, I personally like to know that information, and the image is too cluttered to count the fruits.
~Add a goal of some kind.
~A few more tree types.
I don't know if it is intentional but clicking the tree gives 1000 fruit- If it is intentional perhaps consider increasing the amount per click when you buy more trees.
