First Review-So don't crucify me if I do bad.
This anime is (in my opinion) good for those that are *somewhat* into the Horror genre. I don't watch many horror animes, but if you want to enjoy this anime more than the others, make sure you aren't deeply dived into scary stuff (some interest is fine).
Story 6/10: Looking back, the story is pretty much used in circles (Rinse and repeat). If you do finish the anime, you will have questions and that's understandable considering how i guess, how the studio just dove into it. They never fully explain the background or origin of the game (There's
a manga/summary for it online) or why Natsuko acted the way she did. (Eh, not really a spoiler. You'll notice her behavior change by the end of the first episode). I think honestly the one thing that kept me awake till 3 (yeah i actually stood up til 3 to watch this) was how they handled the rinsing and repeating. They had to handle each situation during the anime differently and it kept me on edge.
Art 8/10: It looks pretty to me. It all comes down to personal preference.
Sound 7/10: I can't fully judge sound since I haven't watched many horrors. I'll give it a 7 simply because I think the sounds were pretty realistic but some effects were wayyyyy too exaggerated (You'll know what I mean if you watch it).
Character 6/10: I never once disliked any character in the anime. However, character development creates character, and there really wasn't any of it. I guess Riona was probably the only one that developed (If there was any) and it was done in a short amount of time. The only time this anime talks about a character's history was Nobu's (basically 1/3 of the anime) and it had some glimpses of Natsuko's past (Literally a few seconds, but they somewhat give you an idea of why she's like that). I couldn't really get attached to any character and sometimes the side ones were pretty frustrating with the way they thought illogically.
Enjoyment/Overall 9/10: I overall enjoyed it. It was probably my naivety that was the reason why I kept watching until I had to stop because I had school the next day. I'm not much of a harsh grader on anime in general so my credibility might not be so good. But if you're (very) relatively new to anime, I think this is a pretty good anime to enjoy. Because once you dive way deep into anime, you're not going to have the same enjoyment of watching this as you would being an infant to anime.
