Originally, I picked this up just to give it a quick look. I didn't really intend to finish it or play it seriously...
However, the game is tiny, so I ended up finishing it anyway.
Now, to an extent, it's to be expected. This is the circle's first game ever, and it's pretty rare that first games of these type are particularly impressive. The only thing that's impressive is the art, and that's if you like the particular style. Everything else is so-so.
Before anything else, this is more of a corruption game than a NTR game. I say this because the NTR side of things feel like they've been thrown in for flavor more than anything else, and the events that lead to Liena getting dicked are more along the lines of rape/hypnosis/magic-drugs, with only one dude actually "beating her with just dick". That's the mayor btw, who has the only full on proper NTR story, sorta, except like everything else, it's too short and too rushed.
The NTR feeling is further undermined by the situation with that guild lady who's a retired adventurer. She's been cursed to lose control of herself around dicks, but is otherwise perfectly normal. This is what seems to happen to Liena in one of the endings, so when she says that she still loves the alchemist dude, I'm inclined to believe that it's true. She just can't stop herself, and it's not really a matter of willpower. This is further emphasized by the fact that you get this set of endings even if you dodge all the H aside from the one unavoidable body-check and rush straight to the bottom of the dungeon.
Beyond that, I'll note that the gallery is not 100% fully complete. It lacks the mini-events and change in pose art that happen when Riena is under the effects of aphrodisiac gas in one section of the dungeon, or when she's under full hypnosis in the last section of the dungeon. It also lacks the short scenes that happen during the "reached the bottom of the dungeon" ending.
So people going for a full gallery save might think that the game has even less content than it actually does.
However, for a dev's first game, it's actually pretty decent in terms of content. I've seen bigger games with less content than this one tbh. For the purpose of "getting material", this game is actually pretty decent. Not so much if you want some actual gameplay and story in addition to your smut. Even ONEONE1 and the like are notably better in that department.
All in all, an ok thing to spend time on.
Oh, and, the translation. As always, Dazed's translation is vastly superior to every other MTL out there... but as always, it has its issues and I'd prefer (and replay the game) with a manual translation. GPT had issues when Liena's speech was intentionally mangled because of her ahegao-ing too hard and the like and there's some poor sections in general as per always. Not gonna bother nitpicking every little details... just gonna hope something better comes along at some point, as always.
