This is Jump Jump, an arcade game from Korean developer dgPix Entertainment. It’s a platform game without a jump button: your player character falls, and you navigate him left and right to try to land on good platforms while avoiding the bad.
Oh, and sometimes landing on a special “Show Time” platform will show you a picture of a naked person, a theme found throughout dgPix’s games. NSFW warning, and all that.
This game was just “dumped,” meaning the files have been copied and preserved. The video above is a direct capture from the arcade board itself, but Jump Jump should be playable in a future version of MAME.
