I'd like to get in on the discussion as well. And it's going to be a big post.
First, the good:
Let me start by saying that your game is the second-best succubus game ever (Myusca for the win) and has potential to be the best. Definitely top 3 with Succubus Prison: House of Lewd Demons and The Last Sovereign. The art and writing are excellent. Not all succubi are memorable, but many are and that's more than I can say about most games. For me it's the Leafhair, Dhalia (two prettiest faces), Daisy, Argeia, Dritta, the bloodsucker and the Thorn one from the last update (crazy glee on the variant where you defeat her). Honourable mentions - the bound one and the insect were pretty cool too, and so was the Polite Succubus - it had great writing, reminded me of Nemea a bit, but I wish the scene was a different angle, I couldn't really appreciate her beauty in that. Nemorosa, the elite ones from intermissions and the final boss of Ch. 4 are very nice too. I can review each Succubsu for you if you want
I still return to check on this game after I forgot many others. I also appreciate how you engage with players here and are ok with the game being accessible. That being said, I hope you understand the following is not meant to discourage, but to help improve the game that I like a lot.
The bad:
- Cutscenes. I get it that you want to tell the story of the world you built. You put in the work, it is understandable. However, it feels a bit like a Dungeon Master describing his world to players for an hour while they want to get in on the action. I'm not saying the scenes are bad or badly written or anything like that, but they are UNSKIPPABLE and that is a bit of a problem. While I actually became interested in the story with the fugitives and the elf, I don't really care about the other hunters. I just didn't develop a connection with them. I understand it all connects together, the Embodied sun and his THICC sister, Kalim's cult being involved and all that, but they are not interactive, not skippable and very, very long. So in these cutscens I'm just holding ENTER and CTRL because holding both seems to make them go by faster and quickly read bits while doing that. The skipping is not fast like RENPY, I'll be holding these keys for a few minutes. It's not a case of skipping to the hentai content, because your writing is good. It's more like you have a book that flips between several characters and you hate one of them and just want to skip ahead. Or like that anime show with the spider, some isekai thing, don't remember the title - it flips between a cool spider plot and a boooooring human plot. It's kind of like that. Keep the scenes by all means, just give us the choice to skip them. Perhaps in a way where you show the beginning "Character B arrives in city C" Watch scene? "Yes" (default) "Summary" (shows a quick summary of events in 2 or 3 text boxes), "Skip entirely". Sometimes I'll watch them, but I'd like to have a choice.
- Weak monsters. I get why they are there, but these fights are very boring. At later stages it's just clicking repeatedly to attack them so you can get on with the rest of the game, even if they die in one hit. It's filler content. Perhaps just do a slash animation on the map with instant defeat of the weak monster? Or only add that after you are strong enough? "Cutting out the boring bit" is usually a good tactic. 2 or 3 interesting fights like the optional bosses are a lot better than 50 repeatable filler fights.
- Pacing - it is not a big deal, but was noticeable in the last update. Maybe it's just a one time thing, but almost all the succubus content was clustered at the end of the chapter. I feel that it's much better if it's spread around a little.
Ideas/suggestions, questions and such, let me know what you think about them if you have the time:
- Lunar clan still feeds on sacriffices, yes? Perhaps they could have a system where the people they live with will offer them a bit of energy, one orgasm per person and they have to excercise their will to let people go after that. Maybe it's even some sort of a public ceremony in the town square or something, people queing up to the kind-hearted succubi to offer them a bit of energy. Only when the victim begs them to take their life, they will unleash their true nature and take pleasure in the drain, showing a different face?
- Some more body variety maybe? The imp was a nice change of pace. I understand you prefer huge, thicc ones with enormous boobs. It would me cool to see some slimmer ones as well. Maybe big thighs, tiny waist, normal-sized boobs? Or a really thin one that just couldn't hind a human and her body regressed to a a very slim one?
- Maybe some bestly succubus that eats its prey whole using the tail (optionally spitting the carcass out after) or eats the "leftovers" that way? Not sure it would fit the setting though.
Conclusion: I believe you are wrong in saying that there are tons of games on this site and on the internet that will cover your needs. That is untrue. There are no games like Succubus Covenant. There is only Succubus Covenant. (and that prison one). This is probably why some of us really want to see this improve rather than move on to something else.
I hope this critique is helpful and thank you for a wonderful game.
