Really? I just tried it. Are you using 8-bit mode? Maybe that affects sounds.
There are some attributes related to this to enable and disable sound and also to test whether sound is on or off. I used these in 'Igor's Quest'.
Sure. I tried both modes again and got the same result.
start_at = my_locationlocations { my_location : location "You are in a room." ;}on_command { : match "test -" { : end_game ; # : win_game ; }}
