Yay, La-Mulana works. Note: To get it to work, you'll need to wait a while for it to start up, then use alt+enter (you may need to change Parallels so it isn't stealing this key combination) to enter windowed mode. Then minimize and restore it. Future runs of the game should work properly, and should start up quickly. If you try to play in Full screen mode, only sprites display, and their bounding boxes display. You end up with a really ugly flashing neon thing that epileptics should probably avoid seeing.
