Penta² (pronounced Penta-Squared) is a casual-oriented puzzle game where the player must create matches and chains in order to achieve high scores. You do this by changing the properties of boxes in the game.
The basic jest is that you have 1 minute to score as high of a score as possible. You change the block you click on to whatever the block in the bottom left-hand corner is. If there are three or more blocks in a chain, you score points. Pretty simple, still expanding it.
