Magic Castle, a game which was being developed by a small Japanese team for eight months, and it was sent off as a pitch to seven publishers, one of them being Sony. The game never made it to shelves, but thanks to some specific emulators and a veteran from the team who was making the game back then we can play the game now.
The veteran we are talking about is PIROWO, turns out he found the source code for the project. Hopefully, he decided to complete the game and release it for everyone to play. The game also received some modern touches like customizable UI etc.
Sonny was pretty satisfied with the project back then but told the developers to work on another project anyway. But at the end of the day, we got to see the game and play it now.
