Mine has to be Dragon Quest: Rocket Slime, a DS spin off of the Dragon Quest series that sees you playing as a slime operating a tank and rescuing the people from your town. You run around the overworld, collecting items to use as ammunition and saving money to upgrade your tank. The art and music are just as great as you'd expect from the Dragon Quest series. It made fantastic use of the DS's dual screens. It's also written for a younger audience, so a lot of it is just really silly and fun! Try it out for sure, I'm so sad there's no sequel :(
I was definitely a bit put off by the graphics from the Hex, and didn't really get the references to it in Inscryption. I might give it a try since you're recommending it.
Pony Island was a hell of a game, though. I remember watching the gameplay videos and being impressed at how innovative Daniel Mullins games were.
