I downloaded it, but there's a problem: My previous saves don't work (Via: Loading screen literally not updating, maybe I'll check it back again to see if it's just gonna take some time to load, besides that, everything else is okay)
Edit: Found another one, when going on top of the roof of the school, your controls disappear.
Edit 2: Nevermind, the Dlsite version only goes up to before the first boss fight, that's why none of my saves don't work.
