Go to patreon and download joiplay (all free), you also need a plug in or 2 but i cant remember which ones rn, itll tell you when you go to boot the game up. Then download the hotel file that's for android, might have to extract files (been a while since i did it). Once that's done then go to joiplay and hit add game, click the download/find the main game file, name game, build number, and date. Boot up game.
