Rodent's Revenge is a classic cat-and-mouse game. You, as a mouse, have to outsmart the cat and trap it in a 1x1 grid by pushing blocks. If the cat gets you, you die. As you beat the levels, more cats will appear and the game gets harder. In the harder levels there are new obstacles, such as purple balls of yarn, sinkholes, and mousetraps.
This is a simple game - there is no sound, and there are a total of 11 different colors. I can see why some people wouldn't like this game and would think it's boring, but I think it's a great classic. If you're looking for a simple, well-made game with great gameplay, get Rodent's Revenge.
