As beautiful as the game looks, I always found it to be the weakest Wario Land game of the bunch.
It was slow, and the gameplay just wasn't that fun. It also felt a little too clean for a Wario game. Especially compared to how crass and crude...
More transformations is the big one. I recall fiery Wario, frozen Wario and snowman Wario, and that's all I can remember. That's kinda sad compared to the earlier games.
Probably more interesting level themes as well. I like some of the level...
Make Wario more fun to control/move. (I don't know how to specifically fix).
Make Wario able to run without needing to use that red pipe machine thing at the end of the level.
Make motion controls optional.
Saw this fangame on the Wario subreddit, so thought I'd track down the original Super Mario Bros X episode release post for more info. Looks pretty good I'd say:

So, anyone tried it out?
