Is it possible to set the game so that it doesn't show the objects and exits in the room by default when the player enters?
I want the player to use commands/verbs to discover the contents of the room.
I can't see an option to disable this.
Assuming you are on the downloaded version (not sure about online version), on the room descriptions tab under game, you can set these values equal to zero and they won't be displayed.
Is this what you mean?
You can do this on online, game - room descriptions tab, deselect the options you don't want.
