Hello fellow Godot developer. I couldn't play it because I guess you developed it with a GLES3 renderer.
Old hardware can not open games that are made with GLES3 renderer. For example, my pc does not have a graphics card and it can't open Godot GLES3 projects too. So I develop games with GLES2. It's about computer hardware. If you wanna reach more people or develop android games, you should develop with GLES2.
