Hello! Welcome to Feedback Quest 8! My name's Hythrain, a co-host and one of the streamers for this event! This feedback is being written live as I stream your game! If you're interested in seeing my live reaction, let me know and I can send you a link to the VOD once it's posted to YouTube!
So my normal approach for any game in these events is simple: I get the game, make sure it's not a virus, then play it with as little information on how to play as possible. This way, I can judge how intuitively someone can figure out the game. Only if it's obvious that I need to read more will I do so. I note this so you can get a sense where some of these feedback comes from. In addition, I want to note that feedback and rating are different; don't use this feedback to gauge what I'll rate, nor should you view my rating as entirely indicative of my feedback.
Okay, so fun fact: I normally don't remember the names of people who submit games to FQ events unless they actively engage with my streams or I regularly see them in the Indie Questing Discord. As such, when I first looked at the screenshots here and saw "pink haired girl in a Japanese uniform outfit with cat ears," I immediately knew it was familiar. Some investigating later, I realized you're the developer of Sweet Science and that this was a sequel to that game! That said, I have opinions about the fact that the canonical ending of Sweet Science is the protagonist dating Azuki but maybe this'll be corrected in the future with sequel games for every girl.
With that said, knowing you're the developer of Sweet Science also means I know how the artwork for this game is made, which immediately led to me noticing a lot of quirks in the artwork.
Now here's where I have to admit something: much like the times I played Sweet Science for these events, I wasn't really able to scratch the surface of what you have here. Even if it's just a demo, I can tell just by the file size that this game is long. Unfortunately, this creates a problem where I can't adequately give feedback on the main aspect of visual novels like this: the story itself. However, what I do know is that in the English translation there are numerous weird sentences and typos. I also know that your first language is German, so it makes sense that these errors exist. The big question I have, however, is if you have someone to help you with your English translation. I don't remember Sweet Science feeling so strange in its dialogue, thus the reason for my question.
I honestly can't give you a whole lot when it comes to feedback, not unless I can get a large amount of time to play it... and unfortunately, with 159 games in FQ8 and only a few weeks to get through them all, I simply don't have that time.
