is it possible to export the demo to linux in unity? I can give you feedback(I also speak spanish) to see if it works and possibly include support later, I tested the demo using wine and it loads but the mouse doesnt stay on the game screen and 3d models are invisible I also tested the dungeon coup demo and it works but the mouse doesnt stay on the game window but it renders properly and was able to move the character until the enemies dont allow me to escape the attack faster than my character gets up
I couldnt make the demo run on steam by adding it as a non steam app and forcing various proton versions Ill buy it on steam and give feedback but I prefer buying in itch.io to be honest
