I found another bug.
Getting rid of the flesh-eating flies in the caverns *before* you get the marble, then going back into the first cavern room to get the marble, then trying to go back up to the screen with the flies causes the game to freeze with the hour glass icon stuck. At least it does for me. Restoring my game and grabbing the marble *before* ridding the cavern of the flies seemed to circumvent this error.

Yup, that's a bad bug! The most recent DL has been updated to fix that one.
I'll have to fix the no money dart problem, too. Any kind of alteration to the actual mechanics of the darts game is actually a little beyond my abilities! The coding for that (as well as the artwork) was done by Gumby and whenever I look at his script, it's honestly beyond my knowledge level!
Throwing a dart requires you to click-and-hold mouse button down, swiftly move the mouse and release. It took me some time to get used to it, but once I did it works really well.
