I haven’t played it on steam deck, but it might be a little hard. It requires a little precision aiming, so you could maybe pull it off with the trackpad, but I struggle with mouse as it is. If they added some console-like auto aim it would be a phenomenal controller game.
TBH it was pretty barebones, but I did enjoy seeing some of my worlds in stereoscopic 3D. It also scares me for the future of VR (minecraft is a REALLY popular game. If it is dropping VR does that mean adoption isn’t going that well?).
Also, this is specifically regarding Bedrock minecraft. Java has never officially supported it, but there are mods that add the functionality.
