I like the idea of telling a story in disjoint pieces -- it can be done really well. But it is harder than telling it straight (because there are fewer conventions to lean on).
In this case, the story parts seem somewhat disconnected from the actual choices made, and in combination with trying to guess what commands are accepted, I get a little tossed out of the story each turn. The narrative is intriguing, but not intriguing enough to keep me in it. Maybe I'm just incompatible with one-turn games.
Either way, you should give it a try! Clearly some people like it a lot and the investment is small.
