I really think you should focus on one platform first, I'd recommend pc first and then the others should follow 'after' you improve the game so you have the gist of how everything works on your game with that particular platform. I say this not because I'm a pc user, I'm an android user and no, I don't have both. I'm sorry to say that your game is very buggy provided that it's still on development phase so you're practically still on test run.
The UI needs improvement, can be quite confusing for new players. I'm on android so I don't know about other platforms. The characters sometimes looks like a ghoul clay maybe because of porting the game into android? The highlights when interacting with things should assimilate its shape on that particular object you interacted to provide some aesthetic in the game and make it neat looking.
The conversation between characters is dry and rushed, maybe add a bit of complexity in their dialogues. I'll wait for your update on this because it is very important if you want your players to adore your characters.
Maybe add an event that will happen when you reach the threshhold needed for the characters to let you do things to them. Let's say Ai needs 10 affection or love points so you can take a bath with her, add a couple more scenes and dialogue to make it more believable that it's fine for you to take a bath with her. I think you can improve the girls' personality, maybe ask for help with this, building a character's personality is real hard. A woman's opinion would really help your character building.
I like the game, it makes you work and actually do something and makes you think for a bit on how you manage your shelter though it's only for a very short time. When Mary wakes up, it's very easy to manage the shelter. The only real thing you need to do is to know when to take a break or return to shelter to catch the girls on the place they like to hang out.
Lastly, this is more of a friendly reminder rather than feedback. Don't rush the game, you don't have to feel rushed because patrons or people want more content from your game it can ruin your game. Quality over quantity, take it at your own pace, implementing and making ideas takes time. Your game has potential, I just hope you can direct it in the right direction. I'll watch the game's development with hope and amiability.
