I am late but a preview of Ghost'n Goblins for Amstrad CPC 6128+ by Frédéric Poesy, Thomas Ferté and Julien Riet is available since April 2020 after 4 years of development. This preview is an Amstrad CPC+ cartridge image, not an image disk. To access the game parameters, please press space or button 1 during cartridge boot.

BDCIron has done a video of this preview.
