From an with Ryuichi Nishizawa:
Last year, [url=http://www.amusement-center.com/project/emusic/cgi/eggmusic_catalog-detail.cgi?product_id=378]a soundtrack was published for an unreleased Westone game called Tokei Jikake no Aquario (時計じかけのアクワリオ). Unfortunately information about this game is scarce. Do you remember anything about it, or why it was not released? There's only one screenshot currently out there, and it looks like it has a really cool visual style similar to the Monster World games. (On a side note, you wouldn't happen to have any more screenshots or art still remaining from this game, would you?)
"Aquario of the Clockwork" was the last arcade game developed by my company. I had been working and suffering for a long time to complete it, but the location test results were poor. It was an eccentric action game with three player simultaneous play. The graphics were quite excellent, but it was not released, unfortunately. The program is located in the archives of my company, so I do not have any screenshots.
If "Aquario of the Clockwork" were released as part of the "Sega Vintage Collection", would people be interested in buying it? I would be very interested to know. :-)
And then recently:

Il semblerait que le jeu pourrait tourner sur système 18. Ce système est déjà pas commun, ça va être violent. sunny
