In the second building: when you arrive at the electrical sign,
choose the left path. Then put yourself under the electrical
wire (rightmost window of the left path) but keep both joysticks
pressed. (I keep the left joystick pressed up and the right
joystick pressed down, but others configurations should work).
After a few seconds your climber will become red with white hair
and electricity won't have effect on it.
There is a secret password in Crazy Climber. Enter the name
"jordan.ltd" in the high score table and you get two free credits.
This only works on the Japanese and bootleg versions of the game.
(Although the password code is still present in the US version,
the high score table entry has been crippled to only allow 3
letters, so you can't enter the code.)
