You can try, there's a version with in-app purchases, which is like my demo/full on desktop https://play.google.com/store/apps/deta ... incessdemo I think Ren'Py coder is about to release a new Ren'Py build for mobile in the next weeks, so when I have time I'll update all the Android games again... but that won't be quick
Unlike iOS, android doesn't need to be jail-broken to side-load software from third-party sites. I often download software from Amazon instead of Google's Play Store. It should even be possible to install the game from your site.
I know, but it's not worth my time to mantain "yet-another-build/platform". Not to say that 99.999% of people get their games from the various appstores so I would be doing this losing money in practice. On mobile the situation is even more closed-wall than desktop.
