Very poor quality story. I appreciate that the dev tried to do something different, but they missed the mark with this one.
I'm usually against infodumps, but in this case, I would've preferred a long infodump at the start so we can have an idea of what the hell is going on. Ideally, dev would've drip fed us information, but you don't really know what happened and why everyone is acting so weird. The characters know, so they don't bother explaining, but you're supposed to get everything.
The characters are really unlikeable. There's a little brother who is apparently an asshole, but he has no dialogue because MC is bullying him and he's afraid to speak. We aren't told what he did, so we just have to bully him not even knowing why.
The MC is really unlikeable. He has no problem bullying his little brother and is basically his little sister's dog. He does everything she tells him and forgives every transgression, but when his mother, very reasonably demands common sense from him, he snaps at her.
The mother is also not very likeable, apparently very judgemental about her son's transition and is overall incompetent enough to be unable to keep her kids in check.
If that wasn't bad enough, the relationships are forced. I really dislike the little sister and I hoped that I would be given some choices, but the choices are mostly about whether or not you want to tell her she's pretty, massage her feet or tell her that you liked seeing her pee. Pretty strange choices, but basically, you have to be okay with her to even attempt to enjoy this game, because most of it revolves around her.
Lastly, the dialogue is horrendous. Engrish everywhere and with so little information and context, it's impossible to decipher what the hell is going on in most conversations.
Only two releases so far, so there's time to get better, but getting through the beginning feels like a chore. I think the introduction to the story needs to be completely remade. Give the player more information and context, get a proofreader and add more choices. I can't see anyone actually liking the anorexic little sister and having to put up with her really drags the game down more than necessary.
