The lore and stuff seemed really cool, the art is really nice but the story is... Honestly I don't even have the words. Maybe I could find interest if the MC wasn't so annoying and it wasn't so terribly written? Like the wording and all is good, the potential is there but it's impossibly boring and constantly makes 0 sense.
The MC is always agreeing with everyone, even when they're contradicting each other. Victor is making so much sense, even though she thought the same about Vincent like 10 min ago and they were wanting completely opposite things to happen. Does she not have a mind of her own? I get being indecisive, trust me but this has really just been frustrating. I read in other comments that you plan to add more options, but it just doesn't seem fixable how much thought text there is and all the while she still seems impossibly thoughtless. Like she thinks herself in circles and never seems to get anywhere beyond "EVERYONE IS SO RIGHT!!"
And HOW would she even know if Vincent is right that without her ability to amplify powers, none of them would even look at her? She doesn't know any of them and since meeting her they've all thrown themselves at her, so how can she know the dude is right? How can she come to the conclusion that he's honest? She has no proof of her own abilities, so why is she like "OH random angry dude has been nothing but mean to me but he's mad so he must be telling the truth and be so right!" Nah, man.
Also they're so ridiculously inappropriate with her, like all of them, shamelessly so that the fact she could not suspect SOMETHING is going on, falling for it, and still tryna be like the typical, clueless, innocent anime MC who is totally oblivious to everyone's advances really just doesn't work out. It makes no sense. NO SENSE. You have to decide whether she's open to this whole everyone coming onto her and knows they're coming on to her OR is she totally clueless and shy? Because she seems to go back and forth and I think I have whiplash.
THEN, the whole storming off without thinking only to be convinced it was stupid even though she has already been told ex-machina thing is like... Ugh. There is an actual choice near the beginning for her to decide she's staying there because "I'm in danger" so there is no way she storms off and then is surprised later when Vincent tells her that she could die. Like... Yes, they said that only 50 times, I get you're confused but you don't SUDDENLY start caring that your life is in danger because the mean dude followed you and continued to be as mean as when he initially caused you to run away. Maybe a different catalyst is needed in that situation because "my feelings are hurt after enduring two days of Vincent's insults" is kinda a really shaky plot device at this point.
Which leads me to otome trope/plot device cliche #1: She has to be in love with dude to amplify his abilities. That's like... So not even necessary. I can see them vying for her attention for the mere fact she can only amplify one person at a time. How the heck does her ability even tell she's in love with someone? That's some serious Disney princess insanity, right there. Like the characters try to give these scientific explanations but lo and behold the MAGIC OF TRUE LOVE! Seems like it really doesn't fit, it's just there to try and push a romantic plot, which... seems super unnecessary, they can try to use her without the magical love thing in fine print there at the bottom and on top of that.. How do they even KNOW THAT? Vincent says there have only been a handful like her, how do you scientifically explain an ability activated by "love". I mean if we're talking endorphins here, I'ma go out on a limb here and say that I don't think it matters much how much you love someone, if you're fighting for your life against some time altering monster thing... I don't think your brain is going to be producing much dopamine or any other hormones relevant to love and affection, but I'm not a neurologist so who knows.
I get this is a demo, but it needs a lot of work, Imo. I mean there's some potential but for the most part, I don't really expect to be wowed. But the art is really well done. Super polished, the lore seems super interesting but beyond a shallow smut oriented story line, I'm not entirely sure what the actual story is supposed to be about. They're going to fight some Atlids! To what end, I'm not sure, but I'm pretty sure that's what's happening. Probably gonna fight them naked too. I'm not sure.
