I finished it, it took me about 6 hours to finish, and I'll be honest, I had fun. It was a cute story and it was nice to explore the world. Gameplay is repetitive, though, to the point of tediousness.
The game basically breaks down into "three worlds," your local neighborhood, a mall, and a carnival, and in each (for example), you have an apple bobbing miniquest that you need to repeat three times, so you end up doing the same apple bobbing game 9 times. While you can switch up your costumes and you get different opponents over time, the opponents are essentially just reskins of a few variations, and the costumes do offer real variety, but with only three moves (one only available every three turns) how you handle the fights is very much the same from fight to fight.
The game is strongest with its side-quests, like the costume contest, or delving into the patriotic costume conspiracy, or rescuing rebellious grubbins. If the game had been a quirky point-and-click adventure (what Double Fine excels at), I think I would have rated it higher; the gameplay feels more like padding on what makes the game fun.
It is not worth $10 bucks. After watching the cartoon (which was fun!) I picked up both for $5, and that felt like a decent price. I don't feel ripped off and, like I said, I had fun, but unless you're really into this sort of game, I would skip it. There are better "cute/weird JRPG" knock-offs.
