Yes, btw. I’ve borrowed some of the newbie bits from Mrs. Pepper’s into my game, especially I’ve been successful with use of ExtraHints. Around 35 messages carefully arranged through the prologue guided the player from the first message explaining something like “you can examine any object mentioned in a room description, try typing EXAMINE T-SHIRT now” through explaining basic actions when player examined different objects (how you can open a box, wear clothes, navigate through rooms, etc., how you can communicate with NPC (in several steps) and so on through helping with steps to first few puzzles where the hints became less concrete about exact commands and more to assure the player how he can think about overcoming the puzzle. Every hint was displayed after game output in light grey so it can be easily ignored.
My game was a special challenge in a puzzle hunt game for children aged approx. 11-14 years old and in the end it was successfully finished by more than fifty teams of (up to) five members who previously not even heard about the existence of text adventure games. They were just thrown into game as a surprise on one Monday morning and best of them finished on Tuesday afternoon. And to this day I’m sure that carefully crafted context sensitive hints presented in short simple messages through the prologue of an actual game was single most important feature which allowed them engage game and start playing so smoothly.
