According to Aldostools, who posted about the discovery online, the early version of the game was recovered from a DECHA00J unit and appears to be a QA build for testing. It was originally dumped and released online by the Hidden Palace member Antviau and is now available to download on the Hidden Palace website as well as Archive.org.
In case you're unfamiliar with Dancing Eyes, it is a bizarre puzzle title from Namco that first debuted in the arcades back in 1996 and has often been described online as a 3D take on Taito's arcade classic Qix. Much like in Qix, players are tasked with maneuvering themselves around a screen to draw and complete a bunch of squares and rectangles. However, instead of exploring an abstract 2D world, in Dancing Eyes, players take control of a small monkey whose job is to crawl across women's clothing to strip them down to the bare necessities.

But it never ended up being released, with our friends at Push Square speculating in 2012 that the risque premise that saw the game being described as "weird" and "pervy" might have caused Namco to get cold feet.
