Ilija and I put this 8-bit retrotastique game together over the course of a few evenings. It served as a nice coding distraction while we worked on something bigger, but we are happy enough with the end result to share it here.
The "standard" instructions ...
Put the pixels faces together as quickly as possible! Juggle the pieces as you assemble your face, mixing and matching in order to beat the timer, and gain a great score.
Use the mouse or arrow keys to move a piece into place. You score more points the more complete the face becomes. Don't slide a piece into a space that is already occupied, or take too long, or you'll lose a life. The timer gets faster, the decision time available less, as you race towards the finish line.
The more "complete" a face is, the more points you get! Clear the whole board for a mega bonus.
