It seems to go straight to credits on a new game for the Android.

There's a high possibility that this is because the public builds are Godot 3 version, although I can export the android build, when these builds were online for Patrons, Godot didn't had an Android exporter back then. Since this may require quite a lot of time to test on a very old version of the game, I will remove the android Builds from the Public versions until we get to the Godot 4 versions where the Android Versions are working fine.
Thanks for repporting.
