This game was available in the mid-1990s on Amuro Namie’s official website. It is a DCR file that cannot be played on recent browsers.
You can download an old version of Netscape Navigator (ver.9 works) as well as Shockwave plugin and open the DCR file with it.
Click on the image below to download the game.
As a bonus, here is a second file that could be found on the website with a dancing Namie that shouts “Body feels!” when you click on her.
