I seem to be able to generate new maps without the need to recycle my older ones. Also when I completed a square where I can find a map tile, it does not tell me I have a new one (nor list it in the maps list).
Good first game! Try to add an demo image of what it should become, maybe some features like total amount of moves or a timer would make it more interesting.
So far I have added the move counter and a preview of the picture already. More yet to come!
