A Day At The Crystal Market is a chill, low-stakes, all-ages rpg about being a child wandering a magical market, buying crystals.
The PDF is 18 pages, with some nice simple illustrations and a laid back atmosphere.
Crystal Market uses the Carta engine for its mechanics, so you play by wandering a game board made of playing cards. Your objectives (the crystals you need to buy) are visible, but everything else is hidden. You *are* on a timer, but 'losing' the game isn't really a loss. The game's energy and voice are similar to a middle grade book. It recognizes that you're (at least playing) a child, and so Crystal Market's losses are experiences to learn from and reflect on, not a punishment for failing to perform at an adequate level.
As far as writing goes, everything in Crystal Market is consistently cozy and charming. The prompts for each card are creative and expand a little bit on the world, but they don't crowd the players imagination, and they always keep things oriented on "what do you do next?"
Overall, if you're looking for an rpg to play with younger kids, this is probably my new top recommendation. I think it'll also be a neat experience for adults who like reminiscence, *and* it's a really good example of a game that feels weighty and meaningful without ever losing its fun. Check it out if you can.
