A clever and unexpected use of the T-Engine 4, Mosaic has a lot going for it. This exploration of pastel tile flipping is uncomplicated but provides a quickly escalating challenge level.

The master stroke here is the procedural music. Notes will frequently pulse across the playing field, creating a melody that becomes richer and more complex with every new tile that has been touched. This has no effect on game play, but it is far more delightful than simple repetitive background music. The first levels are worth spending extra time on just to explore the way the notes develop before enemies begin to interrupt.

The biggest improvement needed in the current version is an upgrade to the enemy graphics. The basic capital letter mobs look somewhat out of place within the musical whimsy of the overall design. Another potential improvement might be the addition of a score. Currently, progress is tracked solely through the number of levels completed. This has a certain appeal, but a running score based on enemies eliminated or combination moves performed may add to the interest level.

Overall, an interesting change of pace within its category. Those who enjoy pure puzzle gaming should be pleased.
