common, it is just a possitive criticim.
any of the roles you are looking for read your post, and they find what it is about only a guy asking for people who make their game witout direct payment, no heavy support rol on development (art/modeling/code) but ofc the guy will controll the patreon, and keep in total secret what the game is about.
a very hard premise for join!
the other day there was a thread with which other guy exposed the main ideas, what the game will be about, the mechanics that the game will have etc etc. In addition to an exquisite technical manual that makes any programmer happy to join and still not be something stealable from the writer. but he sinned in not being aware of the workload that this entails for the other roles. which for them would be the same as finding someone who will not be grateful for the effort they dedicate to the project.
I think it will be much easier for someone to get in if you do a small part of the game first. In this way you will not only be able to help in the development, and be a weighty member in the project, you will also generate more confidence in whoever joins.
