Update: thanks to Susumu and Matt we found out that this obscure RPG was really published in Japan with the name “Lagnacure” by a company called Artdink. You can find more screens of the released version at Snesorama!
Laguna Cool is a cancelled (?) RPG that was in development by Sony Music Entertainment in 1996/1997 for the original Playstation. The game was available at the Tokyo Game Show 1997 but we dont know if there was any playable demo or it was just a video. A single screenshot of this RPG was found by Celine in PSM magazine #3. There are pratically no info on the project, at least with the Laguna Cool title: could this game have been released with another name in Japan? If you recognize this screen, please let us know!
Thanks to Celine for the scan!
