I'm sorry about the last comment ( this is EDITED )
I was reviewing a bunch and messed up the game pages, I pasted the wrong text ( it was for a another game )
I am playing in Linux and unfortunately I couldn't open the game :/
Maybe you could export your Godot Project for web??? It's pretty easy and it plays well on Itch
I'll paste here my terminal output in case you're curious. I'm on NixOS with a Wayland COSMIC Desktop Environment in an Intel Thinkpad Laptop
