Crash all the time
This game is beautiful in its simplicity but it crashes so often that you spend more time restarting the application than playing. The game do remember your position before the crash, but its simply too annoying.
Unless a stable version is released, stay away from this title.
UPDATED:
I also found out that if you increased difficult to hard (easy, medium, hard), in some games, the application crashes immediately after your first move.
