the game is progressing so slow because for whatever reason the dev decided to make branching paths of a very complex party event.
2 potential girls to bring + each of their routes have several branches at the party.
Right, This is exactly the problem. I imagine it would be intimidating to resolve all these outcomes.
Alyssa to party branch:
Alyssa alone from the party, with Val's participation (1 path)
Alyssa AND Evon with Val's Participation. (1 path)
Alyssa goes home alone. (1 path) - Unsure on this one.
Then we have Val's reaction if the MC hooks up on the Alyssa branch without telling her (at least 1 path)
Val to party branch:
Passed Out MC/Val (probably could be combined to one resulting path, regardless of MC Choice to voy Val or play with Evon)
MC/Val/Evon at the party in the bathroom. (1 or 2, if Evon/Val stay used dildo in partyroom, possible lesbian only branch)
Val/Darius sneaking off to the bathroom (1)
Va/Darius fooling around front of the MC (1)
MC/Val having sex at the party, either in bathroom or with everybody in the bedroom. (Probably just 1 path)
There's at least 8, possibly 10 paths here.
The Developer could maybe focus on one or two paths at a time, and not try to do all 8+ simultaneously, and work on ways to pare them down a bit. Here's some metabranching:
Good Girl Val (pretty much just MC)
Lesbian Val (MC+Gals)
Hotwife Val (consensual with MC assistance/participation)
NTR/Cheating Val (Caused by MC behavior)
One way to move forward fast is to focus on the first two (third is my favorite, but would rather new post-party content of any kind first).
