I really love the mod cause of the great horizontal movement (and small height gain) given by the whirlwind. Problem is that just in the first level I could see at least a half dozen very exploitable sequence breaks that could be performed with the new badge but not without it. For example, Ice Yarn early. I didn't try this on later levels.

Highly recommend playing through the game first without mods instead of with.

Other than that, very fun and enjoyable mod once you finish with the game. Can't wait to use it on the new DLC levels and mod levels.
