From MegaNudge Entertainment:
The objective of the game is easy. Spot the difference between two nearly identical images.
Tap all the differences before the timer runs out. The faster you finish, the higher your score. Each incorrect tap results in a loss of time. When time runs out, you lose 1 of 4 life bars. Once all life bars are used up the game ends. A hint button is available to guide you when you get stuck. Use it sparingly as each hint will cost you half a life bar.
