Mpreg is a possibility if enough patreon member's/people in this comment section suggest or agree with it. however, it would eventually just go to the patreon members to vote if that would be added or if something would be.
(Little loophole for this could be to recommend this game to your friends who also are a fan of that idea or something and getting to become his Patreon members and then getting them to suggest it to their friends and eventually have like a hundred people asking for Mpreg lol)
