Well I guess I have a soft spot for trash games, at least comparing my take with other reviewers, anyways, this story actually touched a sweet spot for me, dunno why
I was initially reluctant to play it as I'm not the biggest fan of 3dcg games, in the end this was no exception, the art wasn't the main selling point for me and in fact I couldn't jerk off to it
Is it garbage then? No, specially when comparing it to the usual slop we see in the genre. What I liked the most about the game was the heartwarming scenes between the two main characters, I haven't seen such natural exploration of sexuality and development of a relationship between the two in a while (maybe I just have the bar too low, I'm honestly not sure), after the end of the second chapter I truly believed in the love between the two and that motivated me to get the true/happy ending
Btw, it is very refreshing to see an NTR male MC that isn't totally braindead (he still makes a few quite questionable choices but is not clinically insane)
Also, yes, the NTR is unavoidable (even in the true ending) for anyone that wants to know, a bit of spoilers in the details:
Regarding the gameplay, I actually enjoyed it, I focused on running from enemies and found a bit of an exploit that enabled me to have most of the items to progression in about 40 mins (about day 3-4 of the game), maybe because of that I don't hate that part of the game, though there are plenty of Quality of Life items to make your run easier (the TP to any dungeon floor and health potions). I wouldn't say it felt grindy
(also, very nice translation, sasuga dazed)
TLDR: The story is kinda nice, the game is about 4-6 hours, probably fine for a session, specially if you like NTR
