I've tried the game for a while now. I'm going to use the names as they're translated by ReiPatcher using DeepLTranslator so bear with me if they don't make any sense.
1) Are we supposed to only lewd the main protagonist ("Darkness") or are there similar paths available to the other characters ("Peach" and the jailbait Loli blonde)? Because I do see that both secondary female characters we get to play as also have their own lewd parameters, and requirements to unlock higher ranks. So have I missed something during my first playthrough? Was I actually capable of disbanding the "Peach" and "Silver" duo, for example? Or am I supposed to have them lose a specific fight to unlock the lewd shenanigans?
2) Perhaps it's due to my lack of findings so far, but doesn't this particular video-game feel like a step down in quality, compared to previous OneOne1 titles? Such as Meritocracy of the Oni & Blade or Ideology in Friction, to only point out these most recent ones. I'm mainly talking about the story, the gameplay and how quickly "Darkness" can become a naughty one.
3) I haven't figured out how to increase "Darkness" exposure level from B to A. It's the only sexual parameter not tied to the Chapter 4 of the story, but it mentions completing a certain event... which I have yet to find. If anyone has any clue about that, I would be happy to have your wisdom bestowed upon me (plus how to unlock the lewd content of "Peach" if there's any).
4) Perhaps I'm too attached to the previous OneOne1 titles, and this is supposed to be hentai video-game after all, but doesn't "Darkness" go from prude to absolute slut in a matter of minutes, and all that within the very first chapter of the game? I really preferred the build-up in the previous video-games, when we couldn't reach the higher sexual tiers without completing a bit of story. Of course we could speed up the process drastically, by losing to major enemies and going down the Bad End path, but that was usually at a loss in terms of gameplay and story-telling.
5) "Darkness" feels overpowered, if compared directly to "Peach", "Silver" and the blonde Loli (I keep forgetting her name because it's a long-ass sentence all by itself for some odd reason related to ReiPatcher). "Darkness" can steam-roll through every single enemy in the game, whereas the duo of "Peach" and "Silver" struggle against some common enemies and usually fail me during Boss fights (unless if I spam healing potions, revival pearls or over-level them to be ten to fifteen levels above the enemies).
6) OneOne1 could have cut the blonde Loli out. She has the personality of wet cardboard or paper mâché, and all of her screen time combined only amounts to half of what "Peach" and "Silver" get. In terms of gameplay, she might be the most infuriating one to play, because she can hit as hard as "Darkness" but she has the resilience of a Tesla Cybertruck's window.
