It's wonderful you've enjoyed the OL games :D! Yes, the Our Life games take place in the same world, so does our older game XOXO Droplets (that's where Shiloh and Jeremy are from). Baxter is the only cameo from Our Life: Beginnings & Always, but you'll meet someone who knows Shiloh and Jeremy because they're another cameo from XOXO Droplets.
And yeah, the Patreon beta does have an android version.
