Hi, dev here! I’ll do my best to explain, but just keep in mind that the current build is still a demo, so some of the deeper explanations are intentionally being saved for the full release.
The Heroes start turning on MC (their creator) because they need her positive essence, also known as the Ehsas, to survive. The basic idea is that MC’s prolonged negative thoughts about her life, along with her parental trauma, have gradually affected the Ehsas over time, essentially corrupting what was once a positive energy -> turning it to Naomidi. Since the Heroes are creations that are heavily influenced by MC’s emotions, that corruption has slowly made them more unstable, dangerous, and obsessive toward her. Hence, they resort to the extreme solution of trying to take her essence for themselves in order to survive (though, some of them have their own individual agendas).
Since this is still the demo, that sequence is intentionally there to show the more extreme/yandere side of the characters and establish where the story can eventually go. If you choose to confront the villain (Shyloh), he’ll intervene/save MC, and the story continues into the next scene from there.
Hopefully that clears things up a little! I understand DNFing if you were feeling lost or the current demo wasn’t clicking with you. I was a little sad to see your one-star rating, though, since ratings can have quite a noticeable effect on the game’s overall score. If you decide to DNF something, you definitely don’t have to leave a low rating alongside it, especially if the main issue was confusion with an unfinished demo.
That said, I’d really appreciate it if you gave the updated demo another chance once I’m able to release it, since I’ve worked on making some of these points clearer. Or, if you’d rather wait until everything is properly explained, I hope you’ll consider checking out the full release when the time comes ^^
