You had me at 'succubus' ... but lost me at the repetitive gameplay loop and everything else. And, unless I missed it somehow, there was no intro or anything explaining the egg timer or its use or what the numbers represent or anything (story-wise, I mean. I know they track your turns). The title of the game doesn't even enter into the gameplay outside of it being an egg recording your used turns on the bottom right. I found this game truly annoying and not fun at all, sorry. Especially with the inability to speed the dialogue up, making me have to sit through it over and over for each attempt.
Edit: Forgot to add that when I got the second ending, two of the screens were pure black. Only the kissing animation ever happened - and even then, only after I let it sit on the black screen a bit. Windows 11 if that helps.
