alt Hacker NewsAs someone who grew up on PC speaker, it's actually really good. The main thing is the item sound effects need some tweaking to be less distracting, probably just shorter. It might also do good to just skip certain unimportant sound effects completely.
As someone who also grew up on PC speaker, I think it sounds significantly worse than Wolfenstein 3D's PC speaker sound where it of course would be expected to be better than Wolf3D in every way.
I think they could have made something a lot better by, like Wolf, dropping music entirely from the PC speaker implementation. Focus on the sounds that matter.
