I would recommend starting a new save that you never mod, mods will usually delay when you can play by days, weeks or months. This will happen every update.
I try my best to design the game in a way where the player should never be confused what to do. If something isn't clear, I'll try my best to make it clear.

Of course
She's just now starting a new arc, so things are stabilizing emotionally for Maria's story. I write stories like a rollercoaster, so if you just went down, you can expect to start going in the opposite direction next, which is up in this case. We aren't at the peak of her new arc yet of course, but there won't be anything near that rough in Maria's story for quite a long time, if ever at all again. I don't have plans, at least.
There is a part1 and part2 system. I'm not sure why the f95 staff didn't include it here, but it exists. Or you can just download the update, which is 1gb.
Next update will probably be around 9.2GB if I keep up with the same amount of content I've been making (which is more than v0.11 and before I feel).
v0.16 however, that will probably be 10GB, but you can still download just the update each time now
The game is already heavily compressed, and now that we have multiple different ways to download it, there's not much more I can do without just stop developing or stopping sex.
