This was an early hit for System Sacom in 1985 and pioneered a format dubbed "novelware", which basically just means "storybook-esque images/text before every stage", with the core action consisting of overhead shooty action gameplay with slow movement and incredibly choppy flip-scrolling between screens, as well as your typical Druaga-inspired "RPG" horseshit. This game received several different micom conversions, as well a Famicom Disk System adaptation published by Sunsoft; I'm only really familiar with this version and the FCDS version, and I can say that the console adaptation got a hell of a glow-up (as well as a promotional manga by Sunsoft's illustrator Moriken, which did as much for its popularity as anything else).
Thus far, EGG Console's offered up several games that were either relatively straightforward to parse with or without Japanese knowledge, or sufficiently interesting or historically significant to justify playing in spite of how opaque or clunky they might be, but Märchen Veil... iunno about this one. The story, which centres on a prince on a quest to return to his betrothed princess after being cursed into satyr form and banished to a wasteland, is the main draw, but even that has its caveats: it's all-kana, so kinda bothersome to read, and it ends a ways into the story—strictly speaking, this is Märchen Veil I, with the rest of the story relegated to the PC-9801 sequel. It's cute, really, but is that enough?
Incidentally, this was a very early work of Yukio Horimoto, who went on to create the company Infinity with some other Sacom alum, and there are some thematic/design similarities between this game and Infinity's Ai no Densetsu Olympus no Tatakai (Battle of Olympus).
