Changing Hearts

Description
Changing Hearts is a 1-player strategy game for the 8-bit Atari.
The player starts on a 3 x 3 board with 9 hearts. At the start, the center heart is light, and the surrounding 8 are dark. The goal is to flip the image, by flipping individual pieces, so that only the center heart is dark. If the player flips the middle, all adjacent pieces flip. If a corner is flipped, all 4 pieces in that corner are flipped. If a side piece is flipped, all 3 pieces on that side are flipped. If all hearts are dark, it's game over.
