Dunno, but if you are a frequent online gamer you probably know that 'minimialism' is a frequently used tag over at Kongregate and that there many other minimalist games that are not text adventures.

Notable examples:

Momiga (http://www.kongregate.com/games/Rogerup/momiga) - one button, one dot

Midas (http://www.kongregate.com/games/wanderlands/midas)

This is not a minimalist game (http://stormalligator.com/this-is-not/)

Pretentious game (http://www.kongregate.com/games/keybol/pretentious-game)
