I’m looking for an audio game that
- is FLOSS, and
- runs natively on GNU/Linux.
Actual human voice recordings (English), no speech synthesis.
It must be possible to play it with keyboard input only.
Visual output is okay, but it must not be required to play the game. So blind people must be able to play the game.
The game must be story-based, so it can be an adventure, a RPG, an interactive novel, or similar.
