I got the game(version 0.23.2) working on Android as a download for off-line play on Android devices using a app called joiplay, as a note you can't find joiplay in the Google playstore you may be able to find it in F-droid. 

How to do it

After getting joiplay you open the joiplay app then you should see a +, you want to click on this then you click on 'Import Archive file', this will unzip the game folder you downloaded, ocne this is selected you will have to choose the downloads folder then choose the game .zip; once the extraction is done joiplay will say "it does not support this game" but this is untrue; you will need to click on the + again this time instead of 'Import Archive file' you click add game and choose the joiplay folder then keep going until you see the game .html select it then wait for joiplay to do its thing and once it is done you can play
