If you wish for feedback, I'm happy to oblige. (I'm stealing that rating style from kinkofnowhere, good idea lad)
--- Farmable garden:
I'm really not fond of this idea. While the garden would unlock around midgame, so that's a good spot for it, because you got the "free time" for it, but I'm just not sure how a Slaver-HotelManager-VigilanteCoverProvider-BasicallyTherapistForABunchOfWomen has time for that. And eat. Not to mention sleep occasionally. Especially since it's a temporary thing that Jin will take over anyway.
0 Interactive phone:
I just can't see how or why it would be necessary or useful, but I also can't see how it would be detrimental.
--- Making sex optional:
I mean, HAREM Hotel. Sex is very much central to the plot and the game, at that point, you'd be making 2 parallel games with vaguely similar characters.
+ Expanding on the "How are you?" dialogue:
That does indeed sounds nice and would make the world feel more alive, I concur.
0 Adding themed music:
Since nothing in the game is voice acted, nothing has sound effects, I just don't bother with listening and mute anyway, but if you want to, go nuts.
-- Remakes:
At a certain point you have to stop remaking content, dude. You'll NEVER be satisfied with the quality of your work, that's because you are an artist, and you are at the unique digital trap where previous generations artists were not, because in your art, the game, you can remake each and every frame one by one. But that's a trap, that way you'll never finish this game. You have to learn when to say "that's good enough", and leave it be. It is difficult, I know, I create stuff, and a lot of it goes into the garbage as well, but sometimes fixing an error, that seems at least moderate to you, which is inconsequential to the audience, simply stands in the way of progressing with the art towards the finish.
++ Side character content:
I welcome any new content.
+ More Explore content:
It is indeed nice and interesting, but to be fair, I'm not here for the city, I'm here for the characters in terms of writing, and the porn, so this is tertiary.
0 Calendar system:
I have no firm opinion on it, good luck!
--- New Main character:
Remember when I said I welcome any new content? Well... problem is, the cast is already bigger than most character focused games I own. I genuinely think you've either reached or is close to the point where any more characters will be detrimental to the story and setting. I mean, you've got the Manager, Android, Felicity, Emma, Autumn, Lin, Kali, Ashley, Maria, which is already 8 main characters. For comparison, Battletech has the main character, Kamea Arano, Raju Montgomery, Santiago Espinosa, as main cast, and that's even arguable, since, Raju basically is not present for most of the game, as is Santiago. Granted, Battletech is not a visual novel, but the campaign is heavily story focused, so I think it is a fair comparison. Not to mention this will further compound your constant remaking of the game, even further delaying your progress, which I already think is the biggest issue with the game.
