It's something with production quality, but also some bizarre hang ups. For one, it's mutually extremely surreal and incredibly cringey at times; there are utterly fantastical, out of left-field stuff in the game (Nevermind everyone wanting to fuck the PC on meeting him, there's an underground strip club run by students, a dojo where everyone dresses up in absurd fighting game outfits and don't address it, a "funny" cat-girl club that stretches real hard to be ha ha many laughs while being the driest thing or anything to do with the nurse) while also being a bunch of western dudes making a game in Japan, definitely 100% Japan, including adding Japanese words and little translation notes after. (Oppai Club! Oppai means big titty.) Of course, whether or not it's in Japan is irrelevant.
The writing varies from going on and droning about literally nothing, telling many a failed joke to sudden whiplash of skipping along ten things with a single narrative sentence at times. The amount of characters starts to become a major discredit in that regard.
The animations vary. Usually it all looks pretty nice, definitely top shelf stuff and the backgrounds actually get some love, too. Effort was certainly put into it all. However, some animations look terrible, like just a lack of any physics whatsoever and just kinda sliding back and forth, while others look great. There is also a bizarre over-exaggeration of everyone's smiles to the point everyone is smiling with their entire gums, showing off their full tooth-line. Here's a hot exercise; smile. Do you show much in the way of your teeth? Do you full on retract your lips like you're a vampire from Buffy? It's full on uncanny valley and, personally, extremely off-putting.
There is also the over-reliance with saucy makeout scenes, except it's done in mostly first person without your body being present, of course. So it's just a girl sucking face at the air and it looks incredibly silly.
The game itself has it's fair share of good, powerful scenarios and set-pieces, but there's so much utter "uh?" moments and the above complaints are all so incredibly common that it doesn't really matter for how long E-S is being lucid, something is going to faceplant and ruin it again.
