Well, I'm kinda disappointed. For it to end just when I thought it was truly starting up, though, I probably would've been more disappointed if there was no after-credits scene(s).
100% agree. I've watched the anime (not sure what route it followed), and only done the Kiriha route, but they could have made that ending so much better. Normally, I'm disappointed when VN's end the way I'm expecting. In this case, I would have been happy if it did (he was originally from the island, the waterworks area was very nostalgic...).
Off topic: I was doing my pre cana classes while I finished Shiro's route. Still passing all the stupid tests even w/o watching the videos.
