You know a porn game fails when you've been edging for a couple of hours and decided to look at some porn to finish the job. -me right now.
At its core, this game's quality is already way above the market, but it could be cut in half. I have never seen a game with so many events and yet so many repeated CGs. You are lucky if an event has a unique CG you haven't seen before. After every boss, you unlock nearly 20 new events for the storylines and yet you will keep seeing the same dozen CGs over and over.
The game is not slow-burn, it's stretched. I think the second chapter alone was entirely focused on scenes where she has bare breasts, over 2 hours of playtime. It would be enjoyable if each scene had all kinds of titplay but it's the same as previous scenes but with less clothing now, and the third chapter is the same shit again but now with bare pussy! OH MY!
I'm honestly rushing through the game right now, at the cusp of her finally doing hardcore stuff but at nearly 8 hours of playtime, watching the same dozen CG and its variations is boring. I would be ok if the reused CGs were in between unique CGs for each event, but most events don't have unique CGs.
I rather this game be half as short, and the creator had invested his time making more assets instead of that Path Of Exile tier skill-tree which is the reason I'm playing on the scrub difficulty. Another argument in my favor is nearly 8 hours of playtime and most of it was watching scenes.
I will still finish this game and even recommend it, but I don't see myself ever replaying it. Too stretched.
Addendum: This game also commits the capital sin of mentioning things happening that weren't shown. No, Ayase-san, you did not rimjob anyone, you didn't drink piss, nothing of this happened just because It's written. Do not mention content that isn't there to be seen!
