Kinda crap.
First, the engine. I didn't get far, but from what I've seen, no reason this couldn't have been ren'py. Unity just never feels right with these games. There is a weird lagging, and you sometimes have to click forward multiple times so the text can continue to fill the existing text box.
The characters are unlikable.
Borderline idiot and coward of an MC.
Little sister who hates you.
Teacher who treats you like a gradeschooler instead of a "college" student.
A bully (whose actions seem to be ignored by other people, like the teacher) who is, even in the game's own words, cartoonishly evil (and may be trying to actually kill you?)
Ex-best friend who betrayed you, treats you like garbage, and is willing to let you suffer, because her current BF has blackmail on her maybe. If you take into account her BF/your bully's intensions towards you, at face value as the game suggests, he is willing to either severely harm or kill the MC, and she intends to help him do it to protect herself from a picture leaking out.
No incest patch, so your sister is literally described as "a girl I think day picked up off the streets."
No choices (sure, pre-sandbox is prologue, so maybe choices come to bear later... but from what little sandbox I played, it's doubtful), so you can't choose to do things like NOT perv on your sister, or to try to fight Todd, or to tell Roxy to go fuck herself.
You gain powers you can suddenly use without any learning or training, and end up somewhere, where the resident plans to kill you for entering without permission (seems like she's even dumber than MC, as if she takes her privacy and sanctuary so seriously, you'd think she'd at least want to know how this happened).
You get sucked off by said being (a short, unsexy scene, that commits a cardinal sin in VN's: you have no choice, it is avoidable. Even people who play games wanting to or expecting to fuck everything still prefer to get a choice in the matter.)
Now your back home, and horned lady announces you should be under arrest, but instead recruits you for a mission. MC doesn't think to ask who she is, who she represents, under what authority she should arrest you, or how he was supposed to know he did anything wrong, and just rolls with it. And she, being as unabashedly stupid as everyone else in game, has no questions for you about who you are, and why you have this power.
Now that the prologue is out of the way, where all the drama was dialed to 11 and everything happened lightning fast because the dev has never heard of story progression or pacing and just wants to shovel the into at you so his story can happen, you are in free roam.
In free roam, you can move to places where you tend to see two options: either events you can't do because the person isn't there (example, go to roof, select roxy, and you're told she isn't there). I mean, no shit. Maybe code your game so the option to select events is only present when the event can actually occur?
And a skill option, which you can't progress with.
Then I ended up wandering in the park or something, and clicking an option, which told me "this isn't available until you progress with sister." Another red flag, because that suggests the story will progress in a static, unchanging way, and you're simply going to click to see events you have no choice in, which will unlock other events.
And then, despite telling me this other character was unavailable, it gives me her interaction screen, and any choice on that leads to a pop-ip saying "this content shouldn't be happening now lol."
The engine sucks, the coding is worse, the characters are trash, and the writing is worse.
And it's all played off in a "don't take this seriously, just skip all my text because nothing actually matters, and fap" sort of way. I mean, it is obvious that the dev doesn't take his story seriously and has put no effort into writing it, so why should you respect it enough to trudge through it, dealing with the over the top melodrama and insufferable characters, while given no choices, just to maybe see a sex scene and have more godawful story spewed at you, that you don't even care about?
So, why two stars? Bad as the writing is, it is at least legible english, and the renders look nice enough. I have no bugs or crashes. If your expectations are rock bottom low and your patience for bullshit and bad writing is high, you might find something actually worthwhile here. So, on that note, I can't justify giving it just one star.
Seriously though, this is most likely NOT going to be worth your time, whether you're looking for a story, OR looking to just fap. This should be a hard pass, for everyone.
