This game might be one of the worst AVNs I've played so far, no offense.
The writing is pretty bad, the whole game is filled with cringe dialogues, cliche situations, etc. with very questionable humor, to put it mildly. (imo of course)
Can't say anything special about the music, some choices were pretty bad and the rest of the music wasn't catchy enough to point something out.
When it comes to characters, I can say that they look somewhat unique but at the same time have some weird problems like too-dark eyes, gigantic eyebrows, or way too shiny hair. Nothing special about their personalities as well, everything felt as basic and "tropey" as possible, at least when it comes to the first 2 introduced LIs. Facial expressions most of the time are really weird and funny, but not in a good way.
Quite basic and sometimes unnatural posing with occasional and noticeable clipping, also a bit overused gestures/poses for example the "Uhm actually" pose.
Lighting is extremely chaotic in this game constantly changing in-between renders for no reason, shadows are jumping all around in the same scenes, and in some moments lighting doesn't make sense and is either too strong or too weak.
One of my biggest gripes was constant "references" or "inspired by ..." moments, some of them were way too obvious, for example whole game's intro with the first scene, ripped off almost frame by frame scene with Clara (Eternum scene with Nancy in the beginning) or "who is your best friend" choice (from the same Eternum intro with only one difference, namely the fact that MC knows Jason for 5-10 minutes). It's perfectly okay to take inspiration from other sources/favorite devs, but there's absolutely no need to do it so bluntly and often.
I was kind of conflicted about animations, it's good to see some casual non-lewd animations but in this demo, they were a bit out of place. Simple camera work would've been more than enough.
I would say some of the "funny" moments in the game felt a bit forced and didn't cause any reaction except facepalm here and there. Humor is one of the most difficult things to write in my opinion since it's very subjective stuff, and this game had little to no funny moments.
The developer should definitely spend some time on proofreading or find someone to do it, there were too many problems with grammar/spelling.
And I would suggest lowering the gloss (or whatever it's called in HS) on the character's bodies, due to strong lighting their bodies were way too shiny, same with hair (specifically MC's hairstyle).
Overall, it could be at least an average HS game once the developer fixes a few things: rework the first ~200 renders (before he changed presets), proofread everything, fix rough lighting/shadows and floating items all around (kitchen scene in the first house) and either change or remove unnecessary animations.
P.S. The font in the main menu is terrible.
