Really good. An intriguing story and told in a way that really dragged me in. I've played a few recently that had interesting concepts and plots, but failed in the story-telling. This one didn't, had me focused the whole way through.
You don't get any info about what's going on with MC or any of the characters in the beginning so you need to read carefully and try to put all the pieces together yourself. By the end of Episode 1 you have all the basic info of what's going on. Lots more questions to come and be answered though.
I have it as a 5 at the moment with potential for Top 25 (which will probably depend on how he handles the LIs - will they be forced? how much player agency will we have?) And at least 2 of the girls I do not want my MC to touch with a 10 foot pole.

Great characters, but definitely not romance material.
There's only been flashbacks and dream scene lewds so far, so bit hard to know.
No idea if it's harem or solo, but it does feel like solo paths with a stronger emphasis on story than lewds.
