I think I have a bit of a critique in that the moving platforms and gates seem to have no visual indicator of why they move in one dimension and not the other. Other than that, the WTF is looked pretty awesome for an alpha. I do think that the platforms that appear and disappear, or move/reset based on the dimension need some kind of very clear visual indication that they do. Otherwise, you're just flipping dimensions until you learn the level.
Then again I've played a whole lot of precision platformers where you don't have the luxury of screwing around. Everything is clearly marked as good or bad, or is clearly marked for what it does. Any game where that's not the case, I begin to wonder why. You can only play so much N+, Super Meat Boy, and Spelunky before you begin to wish what those games do were a genre standard.
