If we go by the spirit of Janet Icthycultro's original 1996 Zine, FishBlade has always been about exploring the full depth and breadth of "Fish" and "Blades" as ludonarrative concepts. Using the exact word "FishBlade" somewhere on the cover is probably best practice just for searchability but I think the content behind that cover can be whatever!
I dont think it has to be specifically Fish and Blade! If you've got aquatic creatures and sharp implements, I think you're on the right track. I tried to leave it intentionally vague so that people could interpret that prompt as they liked!
Another poster mentioned putting "Fishblade" somewhere in your game title or subtitle, and as they said, that might not be a bad idea for discoverability purposes. That's up to you! 😊
