YEAH BABY!!!!!!!!!
After my mentioned hatred for the jet pack controls I was overjoyed to know, that was how you fought the freeze.
I wasted 3 continues on Hatter but that was mainly because I couldn't get the pattern down with the wall of cards. What an awesome boss battle, much more impressive than the final and I'm glad Phediuk mentioned hitting the hat, because I need that extra life for Freeze. I would rank that last level as the second easiest which was a surprise considering the difficulty in parts of the hatter levels.
Now to finish of Bloodlines.
