A multi-level game where you clear panes from a window that have a color that does not match the color of a window at the bottom of the screen.

Every 5 levels increases the player's rank. A pseudo army ranking is used from Recruit to the final General Pane in the Glass.

Achievement Award coins are given at the start and one is earned for getting to a new rank. The coins can be used to retry a round, or knock out a non-matching pane from the top window to help the player get to the next round.

Multiple players can be added and each player's progress will be recorded for next play.

Players names can deleted or reset to the beginning.

There are 3 difficulty levels (each making it slightly harder to get through the rounds).

End of game achievements get recorded in the players list.
