I recommend obtaining downloads from Patreon to ensure you have the most updated, safe, and bug-free PC, Mac, and Android versions, or waiting around 5 days for me to release the public versions here.
The download folder will contain different versions based on your operating system. You may need to download directly from the itch.io website, as some users have reported issues when using the desktop app. In addition to downloading the base game, be sure to also download and apply the latest patch as well. Instructions on how to do so are included in the patch zip folder.
If you are downloading a new release and have an existing version, make sure you download both the new base version and the latest patch for the game. For example, if you were updating from version 0.11 to 0.12, you should download version 0.12 of the game and patch 0.12.9, and then move your save folder over to the new game.
Site? You should be able to download JOIPlay through the android app store. You shouldn't need to go to any website for it. And the second part of my comment was on which version to run through JOIPlay. I would try downloading the Windows version and seeing if that will run through JOIPlay first, as it generally works better, but you might need to use the web version with JOIPlay, I'm not entirely sure.
You're using an old save file in a newer version, yes? You'll need to download the "Old Save Compatibility Patch" in the mega folder and apply that to your game. You'll also want to enable compatibility mode in the debugger afterwards.
If you download JoiPlay from the app store you can likely run the Web (or maybe Windows) version of the game from there. It is not tested or developed to be run on Android, so there may be some issues, but I believe it would be playable for the most part.
Deploying to Android was a mess, and ultimately after four hours of work got me an apk that crashed on start up. Did you ever try JOIPlay like I originally suggested? I tried that out myself to see if it would work, and it seemed to have no problems. JOIPlay is available on the play store, and from there you would just need to download the web version of the game, extract it, and open the index.html file (through the JOIPlay app.)
You will need to download and apply the "Old Save Compatibility Patch (For saves from 0.34 and older)" from the download folder. A plugin in version 0.35 broke old saves, but applying the compatibility patch fixes this. You'll also want to apply patch 0.37.13 to the game as well, and then once in the game go to the debug item and activate compatibility mode. (Patch 0.37.13 fixes a bug with compatibility mode.) 781b155fdc
