Download and install the APK.
Play Protect might say that the publisher is unrecognized,
'Install it anyway'.
Happy Gaming!

Note
This is a re-release of the initial release, which had a typo in the version number (I wrote 1.0 instead of 0.1.0).
The tags have been renamed and the apk rebuilt with the correct version number.
Existing users might need to delete and reinstall the app.
