I played the Steam version for almost two hours (made it to day 8 of 49). I'm not a fan, but others might be.
The art is not bad, and there's animated (Live2D or similar) sections. It feels like scenes are a bit inconsistent, I think they had multiple artists working on the game with different styles. I didn't find most of the content arousing, aside from maybe one of the artists/styles.
Gameplay is ultimately just menu based, with a bit of resource management. You can walk around the shrine, but there's nothing to do from what I can tell, so no point to it.
I found the writing very weak. Didn't always feel coherent, wasn't always interesting, and didn't add much to the eroticism for me. Also, during the streams, you can't actually skip lines of text - you either skip the entire scene or you sit through as everything autoplays. So if you're curious to see all the CGs of a stream, you kind of just have to sit through the weak writing.
The general concept of the game was cool, with the autoplaying streams and how you can pick which ones you want to do. Another streaming game came out this same week (oddly similarly named, too: "No-good Streamer Mirai-chan") which, in comparison, is much more polished on the "streaming" side, as in that game you can type in chat, skip individual lines of dialogue, and it's generally more polished. That game IMO executed on its art, writing, polish way better (at least from the demo, I've yet to start playing the full version). But I liked the narrative setup of this game more, with how you're kind of training a fox spirit to become an adult streamer, and have a much larger range of scenes and kinks to explore. It truly felt like a fantastic setup for a corruption story that transitions into an emotional one, but it didn't seem like it was going for that.
I did think Mirai was a cute character. In the intro she explains that she locked her mountain shrine, shielding it, thus isolating herself from all her followers and the world for a century. And when asked why she makes a cute "mlem" face and says that she was scared of airplanes lol. I generally liked what they were going for with her. Not just because she's a fox girl (always love fox girls) but her character.
There's Japanese and English voice acting. The music I saw wasn't bad, there was one loop I liked a lot.
Maybe I'm just in a bad mood but ultimately: I didn't find it that erotic, the writing was poor to me, and gameplay was uninteresting. Nothing hooked me, so I just refunded to get ~$15 back to spend on something else.
But I don't think the game is without value and I feel bad about dropping/refunding it. It wasn't for me but it's possible it might be your thing, if you find the artstyles alluring or if you have different preferences in writing.
P.S. they're continually adding postlaunch updates and improvements on Steam, and said they plan to animate more stream scenes.
