What is Nanaca†Crash?  Nanaca†Crash is a Flash game which uses
characters from an adult PC game called Cross†Channel (warning,
link is not work safe). Nanaca†Crash is not itself an adult game
though; it's similar to the "penguin launching" game which was
popular on the Internet a while back.  Where can I play
Nanaca†Crash?  It seems that the original site has exceeded its
bandwidth limits, but you can play it online at a mirror site
here. Update: The original author has moved to a new location.
How do I play Nanaca†Crash?  The original instructions are in
Japanese, but it's not too hard to figure out how to play. Upon
starting a new game, press and hold the mouse button to select a
launch angle, and then release it to select launch power. During
the game, if "AERIAL" lights up blue or red in the top left hand
corner, you can perform an "AERIAL CRASH" by clicking the mouse.
Both types of aerial crash give your character a boost - the red
type angles it upwards, and the blue type angles it downwards.
