Hi Zion,
I saw the white succubus on pornhub and eventually arrived here.
You're making a great game, with a great and elaborate story, so even if you disregard my following critique the game will be just fine.
I'm even thinking that if you would use Brazilian as sound, your game would be quite OK. Unless the Japanese are already a big fan of course.
I've read some of the comments saying that it has boring elements or messes with the pacing. I've wondered about that as well, as I sensed there was some truth in that although I played it quite fast. I 'm thinking that the following things can be an element to that.
-Compared to MGQ the story telling in SC doesn't involve the protagonist. Something happens and gives some information but it doesn't really affect you the gamer. In MGQ the information is almost always handed over to the protagonist, through an event, a messenger and so on. There are some things that happen outside his knowledge but they are minor events.
-So for the gamer, SC limits to search the succubus, resist/fail 1st temptation, 2 win/fail seduction in the fight, 3 finish her/let yourself be killed.
As I was drawn here with the white succubus that gives you 4 seduction questions although not all leading to something eventful, but that process makes it much less predictable than 1-2-3. In MGQ it was you the gamer that let the lencubus, imp, vampire girl,... do their "small" thing until it was too late for you. Not you not being ready to resist the strong temptation like in SC. If you resist in SC I think you also always succeed or stop the seduction totally. I'm not 100% sure, but you know probably if there is an event that fails or not.
-A more minor thing is that the lesser succubi have already as good as perfect bodies, while the more stronger types are still developing some parts strangely enough. Or is that something new you thought of after making some of the lesser succubi. Like I did like the part with Gloriosa asking if you wanted to see her nipples on the growing boobs and stay still(and die). Drita on the other hand, seduced you totally with her big boobs while being a total newby. It doesn't feel balanced.
-Another minor thing is the maze trap that steals all your attributes magically, or how did that happen again? The succubi could have bargained you to take them of so they would not kill the victim. Or assaulted you in group trying to take them of. Now it just happened.
Well I hope this helps
