I hadn't played a one-move game before I played I'm Having a Heart Attack and it turned out to be an excellent introduction to this mini-genre. The game puts you in the shoes of an actor starring in some kind of pro-health commercial, one in which your character might be about to have a heart attack in the wake of a poorly lived life. The director's nearby, the camera's rolling and there are a few domestic props and food items within reach. With your single move, you determine how the scene will be performed. The viability of any one performance is determined by the director, whose enthusiastic interpretations of your actions are highly amusing. Each viable performance scores you another point out of a possible 41, plus there are an unknown number of bonus points up for grabs for trying out more meta or 'guess the verb' type actions. The scene loops, which makes a lot of sense in the context, giving you the opportunity to stumble around the set, fiddling with the props in a creative manner and trying on gratuitous emotions as the director eggs you on.
The game is addictive and progress tends to come in waves. One successful action will often cause a rash of similar actions to pop into your head. The director's feedback is also helpful. The more of it that you read, the more you may connect with the game's mindset and work out what other angles might lead to performances. I scored more than half the available known points plus a bunch of unknown points in my first session with the game, and I intend to revisit it to try to find more.
