I recently made an audio-only version of Minesweeper for a game jam, games (that you don't die in!) generally take only a couple of minutes, so it should fit the bill okay (but be aware there are NO graphics :-D):
It made me laugh, good job :)
Cheers Tom! Will take a look later. :-)
Just saw it... er, listened to it. Quite entertaining! I must do an updated version sometime with better SFX, clearer instructions and multiple difficulty levels.
If you're still seeking new games could I suggest another of mine?
It's a retro arcade game.
