HOW TO PLAY:
The main action of Bust-A-Move 4 is shooting colored bubbles into clusters
of other bubbles.  When a bubble makes contact with two or more bubbles of
the same color, they pop.  The object of each stage is to pop all the
bubbles.  If the bubbles get too low and touch your shooter, the game is
over.
ARCADE MODE:  Clear as many levels as you can.
PLAYER vs COMPUTER: This mode is essentially a bubble-busting duel in which
you will be playing head-to-head against a computer opponent.  The object is
still the same, but with one added twist - when a combination of two or more
bubbles is busted, any bubbles attached below that chain will break and then
appear on your opponent's screen.
