This was really cool, loved the style of it being a time loop and how even seemingly small decisions effected the loop in different ways, unlocking new events and paths for future loops. The main through line with Shiki, Len and the overall setting was really interesting. Especially loved the revelation near the end. Len herself was always fun to encounter in a new place, while you did something seemingly normal you learn something about the story for the next loop. I love how Shiki can sort of choose what's "cannon" each route, namely if Akiha goes to his school or not.

All the characters were great, Shiki was amazing again, seeing his perspective on the loop situation was interesting. None of the female leads were as focused individually as in their respective routes in Tsukihime, naturally of course. But all their content was really good and I always enjoyed interacting with them. Even though the game doesn't pick one route from OG to build off of, you get a lot of "post OG" type of interactions, certain characters dynamics are changed to how they would be after OG occurs. I'm happy Seo was there too. Ichigo was a nice addition alongside other new characters like Shiki's doctor and nurse.

Overall the side stories in 10 Nights of a A Dream were great too. Only 2 I didn't like, but the rest were really good. Namely the Akiha, Arihiko and Papa Nanaya ones were great for story and character moments, and the more funny ones were funny. The Hisui one was nice as it used one of my favorite endings from OG as the basis. And the Tag one was initially goofy but had a very nice ending for Kohaku.

Overall this was a great sequel I'm happy I read, another Tsukiverse banger.
