Minish Cap was actually the first Zelda game I played as a kid, and it's still quite possibly my favorite of all zeldas. That game is just a lot of fun to play. The artstyle and color pallet is vibrant and appealing to the eye, the controls are very fluid and work perfectly, and the combat is simply a lot of fun.
Though I don't think I've ever gotten all 20 hearts on that game before due to how difficult it can be considering the time restraints on certain fusions.
