Hello

i wanted to set my kids up with your game, but no luck....

they have only access to a raspberry 400, and your game doesn't run on it (since godot absolutely wants opengl 3.3...)

pity...

Maybe someone experienced with Godot would be able to get it running on a Raspberry, starting with the comments from here.

I don't know about Raspberry pi per se, but its pretty easy to compile the game for opengl2 if you download  the godot engine. I did it for an old laptop.
