Game is actually really great, MUCH better than I expected, I'll make a review where I go into more details about the amazing stuff about this game but there are a few areas where I would like to offer constructive criticism, sorry if these have been mentioned before:
The animations need to loop. This is basically an "industry standard" at this point and there's no reason not to make it so the animations loop endlessly until the player presses any button to progress the scene. It should also be a pretty simple change.
The game desperately needs to decide if it wants to be incest by default or "landladycest" with a separate patch. This should also be a relatively easy change but would do A LOT for the feeling of the game.
There are a few weird sentences, spelling errors and cases of bad English here and there. Not nearly as much as some games on this site, but certainly so much that it's noticable and a little distracting.
The scenes seems to be in a slightly weird order, at least in the VN version, because I'm pretty sure we use the slave crest on "mother" before the scene where we use it on Tora, which is the first scene that even explains the slave crest.
Speaking of VN, and this one might be a little controversial, but the simple fact that this game even works as a VN suggests to me that it's basically pointless making a sandbox mode for it to begin with. As you've surely surmised yourself already, sandbox features suck up a ton of development time but furthermore they don't actually add anything to the story or in terms of lewd scenes. It's basically a black hole of development effort and making all those UI elements and empty hallways and scripts and etc doesn't actually make anyone happy. No player is actually having fun pressing arrows or map icons back and forth, just to end up at an empty location where there's nothing to do 96% of the time. Sandbox is genuinely one of those features that looks impressive and conceptually feels deep but in actual play is always just a bother that takes a ton of time to develop. It's not a HUGE deal for my personal experience since there's a VN mode and I'm massively thankful for that, I just can't help but wonder how much story could have been developed instead for all the sandbox development time.
At last, and this isn't so much a constructive criticism as an earnest plea. I sorely hope Shiroi is going to be fine somehow. Firstly, simply because what's the point of demon magic if we can't save a cute girl from dying. Secondly because it's weird that we just let it happen when we had access to a powerful Succubus whom we never told about this girls heart condition and never thought to do anything "magicy" about it beforehand. It would be extremely unsatisfying if a girl ended up dying because the MC went "Oops, forgot I had access to all these powers. Whelp, can't be helped." Thirdly, it's also even more unsatisfying because it only ever feels like a waste to me to introduce an interesting character just for the sole purpose of killing them off for some cheap shock value, without ever letting that character even have the chance of having some kind of character arc. And finally, I just don't think lewd games and (important) character deaths go together thematically whatsoever. The porn aspect of the game is entirely incompatible with tragedy, feeling horny and feeling sad simply don't go together. Now maybe you've already planned on resolving this in a satisfying way from the very start and I understand that's a possibility and in which case I apologize and then my rant would be completely for nothing and I would look like a fool, but I'm willing to take that risk since this is something I feel pretty passionately about and I hope that earnesty comes across.
