I watched a video review of it and it looked really well put together, excellent for introducing young players to 'paper' RPGs, but without being dumbed down.
I was particularly impressed with some of the mechanics they put in to encourage cooperation within the party. Like, players get "friendship token" that they can as bonuses to their rolls. But your friendship tokens are worth twice as much if you're helping ANOTHER player on their roll.
Also, every time your pony CAN'T perform an action because of a character quirk (like, unable to swim across a river because they're deathly afraid of water), everyone in the party gets a friendship token. Which encourages players to make characters with actual flaws.
Edit:
Here's the review, it's very thorough!
