For me it’s more nostalgia, since I remember playing the game as a kid and the music was bold and iconic (and part Moonlight Sonata). It’s funny though, in my memory it sounded more complex, not just a single square-wave tone. I wonder if there was an AdLib/AWE32/SoundBlaster version that played on my PC.

STRAFE is one I enjoy. Sort of a Quake style aesthetic and gameplay, as a roguelite.

I played this one a number of years back and enjoyed it: Christminster - a sort of ‘whodunnit’ set in an old University college.
