Figured out my problem; apparently Ren'py won't run now if there's a colon in the path? That's new, because I've definitely had games with colons in the name before and they run OK.
All the different types of corruption for Justine are amazing, and it looks like Abby and Eve might be interested in taking advantage of her when she comes back to the prison and is out of it. That kind of temptation might be a weakness. I'm very curious how well it will handle things when the rest of the girls are in play, and the ones welcoming the active girl back might be corrupted themselves, that's a fair number of combinations to account for.
The breeding isn't my favourite thing, but it's interesting to see the progression across her three corruption levels.
The combat aspect seems to be the weakest, with it not having a point so far and not being clear what is meant to be going on, and not having the enemy get raped or whatever if you win.
