im sorry to be a bother with this comment, however i noticed that when you click off the game (settings, diff tab, diff game/browser, diff application, etc) i noticed it puts a pause on the game , music still plays but you dont get any of the herbs or money.
i think you should make a sequel of the game. would be great. more skills and alot more levels. maybe an endless mode with every boss in it.
just a thought.
