Hey there! This sounds like a great idea for a game. The Orpheus & Eurydice myth has been popular in opera, but I'd love to see it finally get some play in video games. And thanks for the enthusiasm! I can't wait to see what everybody creates. You're right about the unlimited potential we're working with here.
Also, it's awesome to see Greek devs! I'm not from Greece, but my family and heritage (mostly Italian & Greek) inspired me years ago to get into classical studies in the first place.
