The penguin moves in one
direction at constant speed unless acted upon by an outside force:
moving the mouse or encountering a wall or border.
If button 2 is pressed when a block is encountered then the block is
pushed.
If another block (or a wall) is behind the first then the block
will shatter, scoring 30 points.
Similarly breaking
an egg scores 500.
An unobstructed block will
slide until it hits an obstacle, sweeping along any
sno-bees in its path and crushing them.
Getting one sno-bee with a block scores 400 points, two 1600,
three 3200, four 6400.
.PP
Lining up the three blocks that bear crosses
is worth 5000 points if they are lined against a wall, 10000 otherwise.
Bonus penguins are given out every so often.
.PP
Pushing on the border
causes ripples to propagate along it, stunning any sno-bees that
are touching it.
A penguin may crush a stunned
sno-bee underfoot for 100 points.
