Well... Technically you can install both. But is required for you as end user, to change Android Manifest in one of the packages, using tools for viewing and editing *.apks. And you must resign it with developer signing keychain. And Android will definetly say that resulting apk is dangerous (because test signing keys). 

(plus I remember to been having a real headache when I was doing it, although I don't remeber exactly how I managed to make it work) 

Too much work for such small outcome :)

Oh, and BTW - there is a tutorial for how to make android package with Renpy AND set an actual package name right (under Step 3)

Did you know, that on Android your app is conflicting with Lunateria app? And therefore you can't install both of them. Because both of you (developers), haven't changed the name of package (that line in Android Manifest - "com.org.androidset") to your chosen name of package. 

Hmm, this Doomsday clock disorder sounds like really good genetic mechanism for controlling population of sapient artificial creatures. If creatures need their creators for "reset" of countdown, they won't rebel, unless they stupid enough, and will be slaves for as long as needed by creators. Is it planned sub story about origin of those species or disease is natural?
