I recently played this game and I'd thought leave my thoughts on this.
This is more of a spoiler overview but I won't talk about any events that happen in the game other than a minor fail ending.

Overall I really like this game, I can see in your profile that you recommend Nothing Special and that shows here as the writing and the tone of the story is treated quite seriously, as lot of Yandere VNs even ones that go more into horror do sometimes lean in romanticizing the yandere character but Yeva is treated very serious which oddly increases her charm.
Speaking of Yeva, her and Gavriil's relationship is a standout and how the writing depicts these two is amazing. I can understand why Yeva thinks and acts the way she does and I like how Gavriil is written as somewhat flawed protag with his more darker thoughts and how he is also written in a way in where both endings make sense for him.
More on the funny side, I like how being caught by a bear is an ending, like there's a canonical route in where all the planning by Yeva is just ruined by a bear.
The art style is also amazing and fits the atmosphere the story is going for. I also think the music is great especially the theme that plays while on the train, reminds me of the bar theme from F&H2.
I would love to see the story get expanded upon if you ever feel like coming back to this.
Either way, I really enjoyed this and look forward to what you do in the future.
