heroes-sound-effects binary package in Ubuntu Oracular riscv64

 Heroes is similar to the "Tron" and "Nibbles" games of yore, but includes
 many graphical improvements and new game features. In it, you must maneuver
 a small vehicle around a world and collect powerups while avoiding obstacles,
 your opponents' trails, and even your own trail.
 .
 This package contains optional sound effects for heroes. Install these if
 you want nifty little noises while playing the game.
