I had to load it back up. This one is kinda weird. I do remember having to do it twice for the coin. Turn the gravity on and jump "over" the spikes that keep crashing down. Go to the end the the goal is to hit the switch. If you can, see if you can gravity the large red knight into some spikes, or even scoot him under the spikes that keep going up and down BEFORE you pull the lever.

The entire level is just a matter of timing. Go back the way you came, grab the princess, and make a run for it. You can either change to the prince or be a skeleton to whack away monsters if you can't avoid them (or get rid of them while luring the red knight).

Hope that helps!
