The game plays and run perfectly, expecially in game mode, but I couldn't get it to install. I eventaully had to install on a windows machine and move the install file over to the Steam Deck and add it that way. After that it was just a matter of setting up controls.

I chose didn't install due to the CD version being the only one anyone new could get ahold of and it doesn't install without tinkering or a better knowledge of protontricks than I have. Moving the install folder was super easy though and worth the effort to play this classic game.
