TLDR: it should be worth your time if you like its humor or at least survive the intro
My first impressions of the game were terrible. I hated everything about the MC—appearance, personality, humor, etc. I still can't say I do like him, but having played the content for [Ep 4 part 1], I see he had some character development. Or at least the 'humor' got toned down considerably.
The humor itself is a hit or miss, and it missed hard for me, especially in the intro. I got the impression it got a better pace/usage as the game progressed. The MC still does stupid things, but it is not in every fckng sentence he utters anymore.
Another thing that improved my experience a lot was not to expect to be able to really give input as the MC, rather to experience the story unfolding as intended. More like a movie experience. That's not really how I like VNs and games overall, but it made this experience go from intolerable to actually decent.
I can't affirm bcz I didn't check it, but choices do not seem to matter much. That's not something I like, and it detracts from the experience for me, and as previously mentioned should not be something you're looking for.
But putting the first impressions aside, the game got better as time passed. The jokes started being used less frequently and better placed. They were no longer only punchlines, there was room to breathe between them. The pace improved.
The characters seem to improve as well. Ma, Auntie, Red, even the fat dude that I forgot the name now xD Considering the "incubi" powers, the interactions were believable for a VN. Red most of all.
What started as a terrible experience became something that made me want to know what comes next in the story, even if I dislike the MC and its role.
So, in the end:
MC: still don't like him and would prefer another approach. He does improve, but I doubt it would deviate too much.
Story: I dislike mind control and supernatural influences in NPC behavior. Even then it was used in a contained way, kept me interested. Good supporting characters/LIs.
Animation: decent enough, but not exceptional.
Renders: good. Some scenes/takes were gorgeous.
Posing: some face gestures and body pose were a bit off, uncanny. Eyelid placement most of all.
Music: sorry, but muted. I don't understand how you guys can stand looping music haha the first two songs played were not bad, but it felt like I was watching a sitcom. Paired with the jokes I couldn't stand (I usually mute the music anyway, nothing particular)
Didn't experience any errors.
