The original plan for the release of the game was 3 romances, the sisters in the current game that are almost completed.
Further support on Patreon and goals added a second set of romances, and specific high paying tiers added backer supported romances (we were very picky with these and turned down many that didn't fit and the backers are not writing them or anything). Later we added a single romance that all patrons got to vote on between prompts/options we had picked out.
The release plan is the 3 romances as 1.0, the backer romance as an update, then a 2.0 and 3.0 release that have the other romances split between them. They are pretty far out though so things may change between now and then.
