Really clever idea for a game. The color scheme is decent and the graphics are clear. The music is pleasant.

The execution is hampered somewhat by the controls. I often had difficulty getting the operators into exactly the right spot, even when I had figured out the solution. Since the game appears to be intended more as an intellectual exercise than a dexterity challenge, I would recommend that you arrange for the operators snap into place.

This was super comfy. It was nice seeing boolean logic in the game - great puzzle game! Good job
