I did a quick search on itch recently and didn't see much either. Good luck on your project, nice to see you doing sth about it, instead of just complaining. Developing for a uncatered niche helps to stand out amongst the constant flood of new games.
EDIT:
Btw, you can play as an elf in Dwarf Fortressadventure mode. Also if you use the mod "All races playable" you can play as elves in fortress mode:
• No Mining or Tree Cutting: Elves traditionally refuse to cut down trees or mine underground. In vanilla-accurate elven play, you rely on gathering plants, growing wood from seeds or special workshops, and trading.
• Grown Equipment: Elves do not forge traditional metal or cut wood items; instead, they use "grown" wooden equipment (like living wood armor, helms, and shields) that plants shed or grow for them.
• Exotic Pets: Elves have deep connections to nature and can bring or tame rare, exotic animals like unicorns and grizzly bears.
• No Alcohol Dependency: Unlike dwarves, elves generally do not require alcohol to survive and work happily.
