I played this game both on Windows 10 and on Steam Deck and it worked fine. I don't really understand the complaints about the controls, yes, they were not that great out of the box on steam deck but I adjusted a few things and, to be honset, it was the most fun I had with this game I've ever had. I still am loking forward to the remaster.

BTW there is one game breaking bug - if you save the game before the Melchaiah fight and quit the game and then try to get back there - the game will crash every time. I have no idea if this bug is present if you play on steam deck since I encountered it while playing on Windows 10. I got around it by switching to the underworld before that point. The bet way to avoid that bug alltogether is to go back to Elder God's chamber every time before saving since I heard it can happen in other places, too.
