As a veteran of later Uchikoshi works, I came around to this off the back of a disappointing experience with Remember11, and was pleasantly surprised. The pacing issues it's famous for are definitely there, but my brain was able to just sort of gloss over them and focus on the interesting parts, which appealed to my sensibilities a lot better than R11. It's very amusing to see the blueprints for all sorts of super-specific details in Zero Escape and AITSF that originated here.
