do you remember "crazy climber"?

If you are around 40years old , you might have played a arcade game "crazy climber".
use 2 joystick no button I thought it revolutionary though I was young .

I loved crazy climber as much as "packman" , I loved arcade game and used to play at Oslo batting center at kabukicho when I was young.

It is a real story of crazy climber that came out from a company at Shinjuku Ookubo.
One day a worker of a game company took a glance at window through Shinjuku skyscraper, that came up with a game climbing skyscraper.

then
crazy climber got a hit in global after that.... as much as packman.
