Played through all the test levels besides Forced Advance on 20d. New animations look nice and slick, puzzles felt fair for the most part. A couple of the levels were way too easy, like the one where you whip back and forth across platforms or using a wall to block a fairy mid jumppad crossing. For whatever reason the introduction to the whip being used to ignore a poke was kind of hard for me to get. After I figured though it makes enough sense. Challenge levels are pretty good, Synchronized Jumping is a bit much to parse all at once though. I kind of lucked out and got it after only a couple tries.
Forced Advance: this level must be torture or something. I spent an hour+ on this and it seems impossible to me still. As far as I can see, once a fairy goes in the bottom right they are stuck unless they're thrown out(the whip fairy could, but she would never have use going down there). On top of that, the blue fairy has to go there so that the toad can be poked. At that point, the only way for her to escape is with a muscle fairy. However, the muscle fairy gets stuck which is game over, since the blue fairy has to be thrown across the pit to reach the goal. Maybe I'm forgetting a mechanic, but it seems impossible no matter how I try to piece it together in my mind.
