Can you make it playable on Android
You can download Joiplay by googling Joiplay it's one of the first results and download it off that website
You can download the plugin off their patreon just Google Joiplay Godot plugin and for me the post that had the working plugin was posted 30 Aug 2025. Download Godot 3.4 version 1.00.60 and install it.
This what I used to get it working. I also recommend once you get the game running adding the WASD buttons as the DPAD is gives you by default doesn't work
