Thanks for playing!
Music is kind of permanently on the 'to do' list until I can find a reliable musician to work with. Same thing with using the mouse wheel to switch weapons - I'm down for it I just haven't quite gotten it to work like I want because of mistakes made when the game was first being developed.
Using W and S to scroll through the terminal text is interesting, though - I hadn't thought to add something like that. I'll definitely look into it.
