lots of fun
this is a great game to kill time with, but i have just a few pointers.
an options menu on the pause screen would be nice. if i start getting bord of the music while playing a round, i have to start the game over to get to the options.
hints come to fast, maybe have an option to turn hints off.
maybe change the board at intervals, like levels, to keep the game just a little more interesting.
and finally, like Hamster-at-Dawn says, id like to see a highscores table. it would give players a greater sense of accomplishment. more than just the personal highscore on the side.
overall tho its a fun game and ill continue to play it even if you dont make any updates.
