Almost 80 percent in and it is pretty good. The pacing of information delivery and foreshadowing is really good. The game is constantly delivering new information, but the gate locking effectively controls the order of the information. The foreshadowing is also good enough that you can see things coming hours in advance. It is also a wonder that it is not that confusing. The connective tissue between characters and timeline is delivered by memorable scenes and repetition, so you often go, aha, so that's how it connects with this other event.
The weakness of this approach is that, for some characters, their best moments and development are in another person's scenario. So it does a bad job at establishing through line of pathos at times, and the 100% completion end for a character can be anti climatic. In that respect, Ei, Minami, and Yuki are the best ones so far, with Nenji being the most compromised by this structure. Edit: That said, it is very impressive how BJ got one of the best character arcs through the multiple character storylines.
I still have Shinonome, Takatoshi, Gouto, and Megumi to complete.
