For anyone wondering why the android version was temporarily unavailable, it was because I was replacing it with an updated version, which can also be downloaded here.
If you're talking about Baldi's Fun New School Ultimate, well I'm not sure when it will be completed, since it is still under development. As for this demo (since Alpha 6 has been finished with the release of the V0.2.5b update), I'm not updating it anymore (except for any minor mobile version updates) because it's outdated, although I'll still keep this page up for anyone who wants to try out this early demo of Alpha 6.
