Four Squared

Q - Rotate center piece counter clockwise
W - Rotate center piece clockwise
Directional Buttons - Move Center piece in a direction
F1 - Restart (You might get colors that aren't very readable, just restart.)
(Xbox controllers also work. Shoulder buttons rotate.  Stick/DPad move pieces.)

Make squares! BPM increases every round. Music and background effects dynamically change as you play.

The current beats per minute (BPM) is on the left. Your score is on the right.

I'm looking to see if the idea is any fun.
