It's... fine. The adventure concept itself, being drawn into a manuscript and being forced to act it out, is a solid one. Where I think the adventure sort of flounders is that within the three pages you have a page of suggestions on HOW to run it, and a page of random ideas to inspire, and then a page of NPC stats, but nowhere does it really tell WHAT to run.

The DM has to make up the actual play that the players will be required to act. Also oddly, this RP heavy adventure has characters use mechanical abilities ("A character from the crowd can use their reaction to give suggestions") which is really weird in something that requires table talk and metagaming. Obviously as a DM you can tweak it, but I just think this document feels more like the "concept" stage and less "production".

However, since it isn't an adventure that threatens the players with the penalty of death, a loose and fun bit of sillyness is still a good choice to keep your table entertained for the night. It's Pay What You Will, and so there's no risk in trying it. Just make sure to kick some money back to the author should it end up being a good gaming session!
