Thanks, glad you all liked it!
Sadly, Sofia route is not yet in the game. I already have another plan for the next update, but she should be a relatively high priority to be added after that.
Sorry, but probably not. Not really my preference. A little chubby or curvy could happen, but don't expect full BBW.
As you can see from the empty "Review findings" option in the apartment I forgot to remove, I do plan to give you a chance to go over what you already know and maybe hint at what you might need to look for next. Hints for the girls aren't planned at the moment, but maybe. For now the content with the girls should be pretty straightforward, but if it gets more complicated later on I'll consider the options.
Well, there's already a character with a split ending that's close to what you're describing. Your choice isn't worded the same way, but the result should match your wish: one choice leads to her shrinking you with the blue pill, the other to you becoming her devoted slave.
In general ending scenes for characters will be a case by case thing, with me just trying to come up with the best idea I have (and depending on pictures I can find). I usually try of course to give an ending that fits the content that preceded it. Can't say if the scenario you wanted will happen again or not, but it's possible.
And thanks again for the compliments, it's always nice to hear.
There aren't a lot of avenues to explore, but the ones that are there have pretty much finished content. I tried to write a couple full paths to bad ends instead of opening a lot of paths that don't go very far. Should be a couple hours worth of reading, all in all, I think? If you want an exact figure, Ren'Py checker says there are about 125,000 words in the game. Of course, that includes all variations and choices and little snippets scattered here and there, but there should be more than minutes, at least.
Yes, there's some content in the free-roam. Two characters, to be exact. The first you should be able to see and click on when you're in the street outside your apartment. The second is slightly more hidden, but there aren't many options to explore, she shouldn't be too hard to find. Notice that characters will not always be present, and if they're not, you'll have to try again next hour.
The full vore scene that's currently in is avoidable by the way, even if you do indulge with the character who has it.
As Asdweqr said, it's with the girl who has the foot licking content. You'll have to lick her foot at least once to raise your addiction to her, but then you can do other things for her. The peeing scene is one of the random tasks she can give you when you ask what you can do for her, but your addiction has to be very high to get that one...
Cheers.
