The stage is prepared. The house is open. Now, you wait.
The author captures the inner landscapes of performance well here. There's the restlessness before the curtain rises. Reflecting this, there's a small number of things you can do in this game, which is randomised in parts. There aren't any obvious goals. You can do things for NPCs - tiny quests, if you will. Regardless of what you do, the curtains will eventually rise, and you will assume your role.
Another aspect of performance: the bleeding over of on-stage roles into how you see the actors themselves. NPCs are referred to by their roles - Chatillon, 1st Executioner - even before they get on stage.
I was attracted to this because I've had my share of performances, with very similar feelings. If you've ever been part of any kind of performance, you'll probably enjoy it.
