Thanks for your nice words. It goes to my heart.
To answer some of your questions:
1) The association with the group "Happy Meeple Players" is not done 100% automatically. Someone has to run a script for that to happen and they planned to do it from time to time. I have asked (a bit late) if they could automate it, like every 10 minutes or 1 hour. I am still waiting for an answer. I don't see why it could not be done. So hopefully, it will work better soon.
You can also join it directly here:
https://boardgamearena.com/group?id=171676682) Level X is known as "Mountain Goats" on Board Game Arena. That's its new name. Same rules I think but different layout/theme. And you can play with more players on Board Game Arena.
3) Yes I am French
4) You can discuss things in the BGA group. Maybe that's the best place to coordinate an action to ask the platform to develop a game you love. Their process, as far as I know, is to get a license first, and then ask if one of their (voluntary) developer is interested in coding the game.
