Finished playing this demo right now, and I must say it was a big surprise, and a real blast too haha!
So yeah, first things first, I usually really dislike games that don't have custom art (well, at least custom sprites). It bothers me when different styles are used, or when I see the same "characters" in various games. I mean, I understand why would you do that - not everyone can draw and / or commission artists. But while I'm not picky about art quality, using stock sprites is something that I can't get over... Now, as I said, "usually". I mean, it still bothers me here, but normally I wouldn't have even tried this game after seeing that. But it was SO intriguing that it was enough to make me bear with it and play anyway. And man I'm glad I did! Even though I can't wait for the updated art with expressions added for everyone and so on, I still got SO immersed that I almost forgot about the stock sprites! So kudos to that! And I also have to mention I like your music choices, especially for the mage chapter.
Now, back to what actually wanted to say. This game is really unique in so many things.
First of, I don't believe I've ever seen a game with a concept like this one, with this weird thing about travelling through different worlds and having a different backstory each time - even if it actually is part of a bigger plan, but still. I mean, I've played my fair share of games with travelling between worlds, but not executed that way. It was really refreshing! I really want to know what the hell is happening there!
It's also well... quite amazing that you've managed to make this into some kind of twisted and creepy magical girl!
Now, obviously, I have to mention Kuro. He's so demented oh dear, I can't even believe you put him as the (only!) love interest! Now, don't take me wrong, I wasn't complaining - I think he's awesome! I mean, he's creepy and twisted, but awesome. I like how he's written, and I like the fact he's the polar opposite of what you'd expect from the MC's love interest in that kind of story. Their relationship seem so unhealty and so sincere at the same time - it's really weird. Now, I'm used to otome games and I like characters like Kuro, so the only bad endings I got were from sheer curiosity (I didn't even try one in the Student chapter) - because of that, I guess I'm missing on lots of hints about the overall plot, but I still got to see that fascinating, sad and horrific thing when you choose to go downstairs (won't spoil the details, you know what I mean haha) . Thanks to this specific bad ending, I'm even more curious about Kuro.
It's also very interesting to see the MC being already in a relationship from the very beginning of a game. I don't believe I've ever seen that done before, unless it's an unsteady relationship where you'll end up deciding if she'll stay with the guy or fall in love with someone else - so it would still be a basically regular otome. I mean, it must exist in at least some game, but not that I know about, and since I've played lots of otome and BL games, I know what I'm talking about haha
Also, did I mention I love Kuro's voice acting? Well, now I did!
So yeah, basically, a very intriguing game that manages to keep me on edge and get me crazy involved.
Can't wait for the next demos and, of course, the full release! Keep up the good work and good luck. And also thank you for making this game!
