Overall, I thought it was a kinda eh/10 first episode but interesting enough even though it felt like I watched episode 4 instead of episode 1, lol. But I guess that's intentional and a way to add more to the mystery. There were some really good sakuga and it reminded me a lot of Yuasa's way of animating at times.
Also, it gave me some really strong Lord of The Flies + Haruhi + Twillight Zone vibes, so I'll definitely watch it this season and I hope it can keep itself interesting.

It got me thinking about it and made me want to know what will happen next so call me intrigued. It feels like a movie in terms of animation quality too (it's madhouse tho so kinda expected) and looks like it has a lot of potential!

I watched ep1 in Japanese first, and then I rewatched it for subbed this time, and I think it was amazing, and I am really look forward for the next episodes :)

Really liked it with my only real gripes being the audio mixing and the weird sound effects that sound like a balloon is constantly being rubbed when doing anything like moving an arm. Can't wait to see where it goes.

I thought it was pretty good, not great but still good. It was interesting enough, had great imagery, and animated. The series describes itself as a sci-fi survival series, so I'm interested to see where the sci-fi elements come in.

It was really weird but there was sort of an intrigue. It was pretty interesting tho

Weird, interesting and intriguing I'd say.

This was fucking interesting already a 9.5/10 for ep01. It kinda reminded me of Wonder Egg Priority because of the surreal landscaping. I could say this is more surreal than WEP. It also became interesting when they showed their powers off. The animations kinda reminded me of Yuasa just like the other comment said, and man Madhouse seems to be producing a good anime this season! I'm very much looking forward to this anime and I hope it ends up as a good one.

From a production standpoint, it is everything I love in anime. It's as if the 90s anime aesthetic was created with modern production value. Not to mention the really quirky sound design. It can be a little overpowering at times, but it translates into a pretty neat aesthetic. From a writing perspective, I was a little confused: they really just throw you in the deep end and hope you swim. But you know what? I like it. Lot of good ideas floating around, and I am looking forward to how they'll build them up, develop the mystery of the school and the powers, and keep us engaged. I have high hope for this series, and I can definitely say that the first episode delivered on what I was hoping.

The OP (ED for this episode) seems to be a banger, btw.

I could sum up this entire episode as "janky", in a good way. For a survivalist/deserted group of people plot, you'd expect some sort of set-up and build-up to the actual isolation but the episode throws you right into it with very little context. There's also some hard cuts and editing that threw me off as to what was happening.

The sound design was great, without any music until the last couple minutes of the episode to accentuate the emptiness of the setting. That last sequence with the opening playing made me smile, nothing felt more summery than returning to the world by plunging into the ocean, somehow. The animation felt a bit like Yuasa, like others mentioned. My favorite part, though, has to be the art and designs. The colors are vibrant and pop, contrary to the simple character designs.

Character-wise, I'm digging this tension between everyone in this musical-chairs game for the leader position. Without a proper set-up before the school was separated from the world, it again feels a bit janky to get a feel for everyone.

Overall, I'm hooked in. A janky kick-off to an interesting mystery worked well, with some impressive production by an impressive staff. Most likely the only thing I'll be watching from this summer's catalog.

Oh yeah, and I loved the small references to Stop!! Hibari-kun!(original character designer Hisashi Eguchi's manga) and The Drifitng Classroom.

I enjoyed the episode a lot. Very interesting premise and I love seeing the different character's perspectives.

How they work with the sound is really interesting. No music at all, just eerie noises until the world is revealed and the music starts playing. Looking forward to the continuation!

Another interesting original anime. Hopefully the quality will remain strong until last episode.

ayo i watched it here

weird, interesting and i loved the animation so.. guess you can say i'm pretty hyped for more. i can see why a friend told me it had the twilight zone vibes!

I really liked the art style, animation and cinematography. Story is intriguing but I get a weird feeling this anime is gonna disappointment me idk why. Can’t wait to see what the next ep is gonna be like.

A lot of people talking about the resemblance to Lord of the Flies. Now I haven't read Lord of the Flies but what I did read was the Gone Series by Michael Grant (kinda surprised no one has talked about it here) and from what I've seen in the first episode, this anime heavily resembles the events and themes in Gone.
Gone Series is basically about a town where a bizarre occurrence leads to the disappearance of every adult in that town, leaving everyone below 17 or 18 years of age stuck with no contact to the outside world. Eventually, some gain supernatural powers and some don't and this creates all sorts of rifts and disputes.
The anime basically showcases this plot, but restricted to a school and high-schoolers instead of a town and minors.

In the end, this is just my take on the first episode and things could change by a lot as the plot progresses. Very excited for what this anime has in store.

i absolutely love the animation

the first ep is good,its strange and interesting and the animation is like devilman crybaby at some parts

Absolutely loved this episode! Excited for more! Very psychological and thought provoking.

Intriguing first episode. Looking forward to finding out more about their powers and the alternate dimension!
The character designs are nice and simple.

It reminds me of Lord of the Flies

The reference to Lord of the Flies got me

I absolutely loved ep 1, this really intrigues me, I really want to know how this show goes

For people who missed some references:

The Group Talk is named after this classic manga:
anilist.co/manga/30970
Which have the exact same premise than this anime.

Also, a girl was reading this another classic manga:
anilist.co/manga/70981-/
Made by Hisashi Eguchi, who is responsible for the character design of the anime.

Also, is the carousel a reference to Utena?

weird but interesting not a fan of the animation and artstyle but it compliments the theme so ill definitely watch it

Went into the anime blind, never heard of it nor did see any PV or read the synopsis.

At first I thought that they really ran out of budget for the scenery - good joke in my opinion.

I honestly didn't expect to like this anime at first since the animation reminded me of Mob Psycho style, which I did not really like but it started to grow on me.

Strong start I'd say. Now will it be a come back from a Madhouse? Eh, we'll see

that episode was really cool, i really liked it
can't wait for the next one :D
i am already in love with this anime

I found the first episode very interesting. I agree with a lot of comments on the Lord of the Flies references, and think it's a very interesting way to show similar ideas and concepts. The art is very neat and the style reminds me of Sayonara, Cramer, which I thought was a very pretty show (plot withstanding). @unhuggity made a good point on the information we're presented in the episode. I think it was a good choice to start already in the alternate dimension, and the fact that we really aren't told anything not only adds to the intrigue, but gives opportunities for us to see what is going on, and to make our own conclusions, much like the characters in the show. I really hope this is built on, there is some strong opportunities for some really good worldbuilding so far.

I'm guessing that the small boi is a God?
