Along time ago around about 2005, Griel’s Quest for the Sangraal was released as a puzzle game entry in the MSXDev competition, with a much later port released for the Sega Megadrive, Genesis in 2017, as a fully commercial product by 1985 Alternative and named as Griel's Quest for the Holy Porrón. So why are we mentioning this game already released some time back? Well you'll be pleased to know one of the creators as Moon-Watcher has released the game free as a downloadable ROM file.
