This is just a simple game that uses a rotating circle cutout of an image that you try to line up with the rest of the image by pressing Space at the right time. Use the Left and Right Arrow Keys to switch images. If you want to make something similar, I pasted a circle on top of a bitmap image, then I filled the circle with transparent, leaving an image with a hole in it. I did the same for a same-sized square, which was pasted on a second copy of the image, and I filled that with transparent, leaving just what's in the circle. See inside to see the costumes.
