You play not!Touhou pvp with him and he dies instantly so i wonder if you can intentionally die earlier to make him happy. You find some scrapped music notes in the thrash and it's clear he was trying to compose something for you.

("you are my hero oniichan uwu")
From the drawings you'll see that Karam is either embelishing these memories or is kinda of mary sueish because he keeps remembering him being the cool guy who teached everyone, was best at games, took fault for his friend breaking the window etc. He comes across as hyper responsible with a slight tinge of depression over his dead mom. One curious detail is that Karam names all his friends but one girl is only called "X", which i assume was his girlfriend and he has a note with her phone in his inventory that says "why do i keep this?". He also has a fuckton of water bottles in his room which is a gag i don't really get.

(What are we, some kind of OMORI?)
Eventually Nayan sleeps and you go the market buy christmas decorations. There you find your old friends, some are cool with you, some wish you'd go out more, some are a bit resentful for not talking with them again, some moved out.

(I apreciate how almost every npc has a portrait)

(oh oh, this girly smokes and dyes her hair, this means she became a delinqueeeeent)

(that's a lot of twinks...)

(At some point it feels like the dev has created too many OCs because it feels dumb how many friends he meets in the span of a few minutes)
And then there is THIS GUY who sounds like he was madly in love me and i backstabbed him for my brother. Any nuance in this story was lost because he has to explain everything and suddendly i realize i'm in OMORI but shit.
(whoa calm down there you're giving me strong yaoi vibes here)
(ok this line was unnecessary after the previous one, you don't have to explain my feelings).
(was it your heart too?)
(oh... OH... That's a lot darker. Karam said "the accident" but i didnt think it would be something that killed multiple people...)
(Wait was X that girl? Was that my ex girlfriend then? oh boy)
Then the combat gameplay start and we fight Ark (who is this guy). We can talk or fight.

(he throws some punch projectiles that are slow. I wonder if i can die in this fight?)
You have the option to calm him down, tell him to stay quiet or ignore him. Some make him mad, one ends the fight.

(i like the battle portraits between talk attempts but wait- FOUR MONTHS? That's all? I thought he ignored you for years or something. Don't you guys live close, are you telling me no one ever visited him? Did he not go to school? what?)
I refused to punch him and ingored him until he left in frustration. Kinda want to retry and punch him to see what happens. Anyways, we do more fluff with our bro like bake cookies and play chess. But then they need milk for the cookies and he goes to the store at this hour in the rain.
Wait WHAT? That's retarded. Why wont Karam go there? This feels extremely out of character and contrived. And it is because we get surprise red flags.

(They have a black cat named Yurim. I forgot to mention it but that name is important)

(haha it sure would be perfect if mom was alive. I miss her so much big bro. I want to stay ith you forever big bro)

OH GOD OH FUCK IT'S OUT NOWHERE GLITCHY EFFECTS! THAT MEANS I'M GETTING-

I GOT MOTHERFUCKING ISEKAIED!
Turns out i changed clothes to something weirdly omoriesque (socks and cape?) and i'm apparently in some kind of magical academy where i'm a student now. The room besides me has a very pretty boy who uses THOU like he's an ol knight or something and he's really nice and polite and wonders why i woke him up, as if he already knows me when i have no clue who he is.

(This fucking twink is overloading my yaoi radar and i do not like it. I feel like it's only a matter of time until we see a cat boy).
We walk more the academy that is shaped suspiciously like my house. That boy whose name i forgot because there is no name in the portraits calls me to "train magic" with our friend laskha. Because apparently we dont know magic.

(*yaoi radar explodes*)
Laschka is a cat boy. He's eager to play with us (oh no). But the way hat boy talks feels like he is hiding something and knows a lot about us and that laska is also hiding someone in the room. He says he's in the room with his sister but laska tries to correct and hat boy goes on. Then turns out that a cat woman comes out of the bed and yells at us for waking her up.

(Lady this room was locked before with this catboy inside. Mind explaining what you two were doing?)
In this fight she taunts us for wanting to train magic so she'll show us how it's done. In a fight!

(for some reason you can chose someone here. Karam name is now "??????" which i find bizarre as hatboy calls me Karam and i ask him about my brother so i remember my own idendity so what???? I picked myself.)

(i think hatboy name is Luminyan which sounds too cat like to not be intentional)
In this battle we have a full party and there is a mechanic where i pick random energy drops that fuel my friends magic. Hatboy gives a shield and catboy throws a projectile, each has their button press. This is interesting but hilariously never comes up again the demo i leave them after this.
Oh yeah, i got a new weapon in the academy a useles magic wand. If i fight with it i throw a shitty stick that bounces and i must get it to shoot again. Otherwise i can punch where random prompts appear in the arena and i mess step and press. Both weapons feel garbage to use. This boss fight is really hard and feels like you're supposed to lose and i lost.

(Fucking LOL you mean, this is the only time they say fuck in the demo)
After this fight we must go to our rooms but then i invade hat boy room and he's not there. I find a key in his tablethat opens the closet in my room, where i go in and get... Isekaied AGAIN! Now to a forest with a cat girl.

(hope you enjoyed those oldschool kawaii desu ne neko neko roleplay girls cause you'll have to endure this one)
I meet a catgirl who is named Yurim aka the name of my black cat. She asks my name and i find it retarded. I input Karam and she says it sounds familiar (hmm). I go back and try others, using Nayan also says the same but others she doesnt mention so i kept Karam.
We go explore the pink forest and Yurim will comment on fucking everything. This is the devs favourite oc and you must love her too. This game is tagged psychologocial horror so i already know this girl will be a boss and/or have a mental breakdown later. She created everything in the forest, every sign, every bridge, planted every tree, etc. It starts getting creepy and you'll see why. We go to her house and tell her our story and she doesnt believe it. She says we should talk to some strangers who also entered the forest the other day.

(girl has waaaaaaaaaaaaaaay to many portraits)
We can also fight random enemies now, they're funny quirk animals and they seem to be upset at yurim eating or pranking them. But i dont know why would pick peace over fight as there is seemingly no difference, no exp or response or anything, despite the steam page saying choices have consequences.

(Karam looks like a fucking loser now wow)
Oh yea, let me get this out of the way first. I did not like the combat. It suffers the same problems with every recent UT-like i played, where there is literally no reason to fight as you only get gold that you dont need if you dont fight. This game doesnt even have exp or a victory screen (seriously it just fades back to map).
But the main problem is that balance is wonky as fuck and enemy attacks are a too long. You can legit lose all your hp within an enemy first attack which is absurd (i think undertale prevents that). Some are also much harder than others and the battle music is this wacky ass clown thrash music.
Anyway there is one interesting bit where the librarian is missing and there is a poster. Yurim says we should move on. We must visit the libraby and she goes there and finds nobody and is sad.

(this was a lil sad but then it crashed my game and i felt upset)
One of those strangers is rose, who looks like a white mage girl. She is ambiguously nice and kinda bland but nice and we have a long talk about the stuff yurim built and i forgot.
Oh yeah, there is actually normal people in this forest and it's WEIRD. Why are there normal people, it's not really explained but i guess there is a teacher and as chool and kids but also talking creatures.

(this guy is a teacher who loves milk i guess)

WHY ARE YOU GIVING ME MORE YAOI FUEL? STOOOOOOOOOOOOOOOP

These ladies ask who is this "handsome young man" and shit and it gives me safe "ara ara pedo mommy" comedy. Yurim says she will bite them first if they touch us.

(the game froze again! fuuuuuuuuuuuuuuuck)

(I respect how many npcs have portraits but this girl in particular feels like a fucking kickstarter OC which is weird as there is no kickstarter yet).
Anyway we go talk to the fisherman to get a fish (wow). On the way back we fight a bee. After fighting a bee a character that looks like a deviantart OC is impressed and challenges us.
This guy thinks he's really hot shit and the shadow coolest and we should be his servant, but in reality he's kinda dumb. You know what this is? It's fucking GREAT PAPYRUS again! In another undertale clone! He keeps ruining a generation of videogames!
As we fight Oskos (what a fucking dumb name) he throws me a shadow knife and tells me to use against him. The knife is an ACTUALLY GOOD WEAPON as it fires a fast projectile up so you can play a normal schmup game. But i didnt do that and i kneeled until his sister appeared.

(Ophelia is a cool vendor who likes money and gives more dommy mommy vibes, presumably to compensate for her himbo brother)
They are together with Rose anda girl dressed as shark who is apparently Ophelia's servant, we talk more and decide to go spend night with them in their cabin. It becomes night and i realize that when i go into this other zone with a portal and back the music loops and stacks on top of itself becoming a demon cacophony.

(actually this girl might be some kind of sex slave or something as she barks for ophelia and calls her lady ophelia with heart portrait)
Inside we have some good talks and Oskos says i should use the knife so it gets stronger while rose says i shouldnt use that shit as Oskos is retarded and his weapons are dangerous. Anyway we have dinner and oskos gets drunk and vomits. Then we sleep.

(cute)
Then we wake up and go outside and we eavesdrop rose talking about how this place is insane and everyone is a godamn brainwashed npc who repeats the same lines and has no lives and i'm like WHAT???
Yurim cries and says the place is totally real and not fake. She says she thought she finally found real friends in them but they never liked her. Rose wants none of that shit, she's out.

Ok so there is a few main problems with this twist. First of all, it comes out o nowhere. Sure Yurim making everything implies there is something wrong but i thought she would be trapped here and others were too, not that this is fake.
Another big issue here is that
Rose is lying. The npcs do change dialogue when you're not with yurim and on the next day, and they all react to you. I did NOT get the vibe that these are fake npcs or something, if there was any foreshadow at all i mussed.
But the main problem is a hard to see which is the fact that this is way too sudden and akward reveal. I do not know why rose decided the first thing she must do after waking up is get away from yurim and yell about hating this place. It's not like she regrets at all and even says "Yurim needed to hear that for her own good" so why would she move away? Why not tell her in person? Or hell why not tell US the player in secret?
It would've made much more sense if she tried to talk to us before and say "hey you're new here right? You notice some stuff is wrong?" and said she was planning to leave and we should consider going with her or something. But in the demo it feels like someone smacked the dev and told them to add some drama right now because nothing happened so far.
And that's the other issue isn't it, until this point it feels like the developer make up too many groups of OC and wanted all of them to hang out and forgot to pace their videogame. The magic academy section is pointless in this demo as you dont return there and feels bizarre to get isekaied again after 10 minutes. Remember when this was about finding my brother?
But here comes the reason i quit, i simply cannot find Yurim after this point. I dont know if my save file is fucked or something but she is not where the video says she should be and i'm kinda bored and tired after more than 2 hours.
There is more to the demo later like Yurim being sad and having a breakdown and a REAL evil force appearing.
