I'd like to point out that the full version of the game is over 5GB in size.
Considering the current demo version has 3GB of 1080p .png's that could easily be shrunk down to ~300MB of .jpg (90% quality), or similar size for webp, I don't think that 5GB is anything to brag about for a 0.1 or 0.2 release. Considering it's over 900 files, it's probably a pain to change in the code (the files are easy to batch convert with something like irfanview), but makes the game vastly better to download, and the size is only going to get bigger as it goes on.
I'd also go and remove ALL of the single option choices. The do literally nothing for the story, and only waste the players time. IMO They don't add to the illusion of interactivity, rather they take away from it.
Disabling rollback because 'narrative' is absurd. It doesn't stop players from going back and changing their choice, it just makes them realise they need to save at EVERY choice instead. Or they just re-enable rollback if they know how (change config.rollback_enabled = False to True in library.rpy in this case). Or they don't care, in which case they're unaffected either way.
The only time I can see a genuine reason to disable rollback is to stop people cheesing the game to get good results if RNG is involved. And even then they can save/load to 'cheat' the single player game.
The debt story line bit is dumb. I'm going to assume this is 'alternate universe' Earth, in the country of Waldolandia or something, where you can be responsible for a debt (to a non-criminal organisation) that you had no part in, didn't sign for, know about, AND where the person who's debt it actually is just fled the country (they didn't even die or anything). Which leads to the next bit of "pay us more money each month than most people earn in a year LOL" is easily avoided by... fleeing the country like dear old Dad did. That seems to foil Nexus corp easily enough. Would be cheaper too, though you would likely lose the house, but with that debt, you probably will anyway. (EDIT: seems that Nexus corp actually ARE mafia types? I misread and thought the MC assumed they were mafia, but they were actually a legit buisiness. The 90k/month, and cheaper to just flee the country bit still stands though).
But I'm hoping that's just a silly/clumsy trigger to get the proper story line going. I haven't really made it that far in, so I can't really judge that yet.
