The levels that are more tailored to Wario's unique moves than 1, but I couldn't stand the game's changes to progression and treasure collection. Cutting the main campaign in half makes the initial run feel really dry, and I didn't enjoy exploration enough to want to get all the treasures and map panels, and levels as a whole get too gimmicky to want to revisit. Even the side worlds kinda drag. It's a shame too, cause every other change to 1's formula is for the better and ups the ante on Wario's appeal. Hopefully 3 and 4 will be closer to my tastes.
