Um.. hi EchoProject.... Just a suggestion(not just for adastra), when releasing an update apk for Android, don't change the package name, like on last month's update, it's package name was adastra.game95, now this month (October), was adastra.game010... um, can you just use one, package name..
Like this...
For adastra: com.echoproject.adastra.game
For echo: com.echoproject.echo.game
im suggesting this to stick to one package name for your every game for Android because when i want to install the latest release of your games, i will have to first is to backup the data then uninstall the previous version and install the latest one and restore the data on the latest version (with different package name)
(BTW: YOUR GAMES IS GOOD!)
