This rules set is around 178 words long, and could, I think, should have been more developed before it was released. It’s a good and novel central idea (we need more game that can be played on a journeys), but I think in needs more far more meat on the bone than what is here.
Four things I would have liked to have seen.
Firstly, I would have like to have seen a way of incorporating large structures/landmarks seen on the journey into the narrative with some examples given (in this field…, at that warehouse…, in that lake…, along this road…, under this bridge…entangled in this pylon) rather than just announcing a mech.
Secondly, how about mentioning themes other than giant Mechs? For example; Under this bridge the rebels hid, from the giant flying saucer that seemed to hover above for hours as the aliens deployed there giant electro-lizards to search the area for human forces…OR this warehouse is where the Vampire Queen sent those who were to undergo the special process.
Thirdly, how about where you start describing a structure but stop halfway, letting another player finish off the second half of that structure’s story, this would throw some curved balls into the narrative, and becomes more like a living shared collaborative narrative rather than individual story splinters.
Finally Thirdly, I would have like some sort of point or scoring system to work out a winner, it didn't have to be complex, how about; at the end each player has to announce the story they enjoyed the most. Player with the most votes wins.
