In case you don't know what F-Droid is : "F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform.".

You can directly download the game application here, or download it through the F-Droid application, as you prefer.

Keep in mind that while your Android will warn you about downloading anything that doesn't have its google signature, every F-Droid application as well as F-Droid itself are Open Source, tldr they can't be virus.

Huge shoutout to ygringas, who helped me upload the game on f-droid. He's the working dev on Ravengate, which is the first Godot game uploaded on f-droid, I couldn't have done it without his help.

Have a good one.
