Hello. I hope this comment is in English, as you requested. I attempted to play this game to the best of my ability, using both screen translation software and my own phone using Google Translate. However I was stopped basically right after the encounter with the doctor with this error.

I wish I had more to comment on, as I am not sure how much content I missed (I saw the 2 characters in the first screenshot.)
I don't like to be overtly requesting, but perhaps you could consider adding an English translation to your next prototype, if it's within your ability. Even a raw copy of the script in Russian would work, as I could translate it faster and get a more complete picture of the plot.
Like the other person who commented, I thought the characters were quite well done! Their style remind me of an artist who's a regular on an image board general I frequent (They have a handle if your artist wants to look, but I don't want to be unwarranted.) Are the backgrounds AI Generated? If not I don't want to cause offence, but if they are I would suggest changing them to something else, like 3D renders. Though It might just be a prototype thing.
Oh, and I think the doctor should have a Sprite, but that's just my personal opinion.
Like I said, I only have a tiny bit of the plot to go off of. Is this going to be some kind of Changed-like game with the MC at risk of transforming, or is it just a plot hook to explain the MC escaping? The point I'm asking if the MC is going to stay human throughout the plot.
Another thing, do Anthros exist normally in this world, or is it weird for the MC to meet them, because the little I saw of his first interaction he didn't seem very freaked out to see anthros.
Anyway, that is all for now. Hope to hear from you soon.
Oh, I'll give slight feedback on what I read, though I imagine some is lost in translation! I thought the basic plot was pretty decent compared to a lot of first time projects. I didn't notice too much swearing, but again, it might be my translation hiding it.
I'm sure you had a local mindset for it, but here in my part of North America there is a major family doctor shortage, so someone looking for a private client to get a sick note and falling for what they think is a "cheap" option is quite believable.
