All the platforms at the time were part one.
Viewing post in Malevolent Planet 2D Demo - May Public Build comments
So the public build has these platforms:
- Windows
- MacOS
- WebGL
- Android
The patron build also has the same platforms. Wait, what apk are you referring to? It appears by accident I left a previous apk downloadable, but it's not supposed to be there so I disabled downloading for it. Now only the part 1 will be seen for the android platform.
