Acorn Arcade review Mice is a simple exterminate the rodents game, built around a point an click engine. The aim of the game is to eliminate all the rodents on each level which, although it sounds easy, requires a bit of skill and a lot of luck. You have various weapons at your disposal, but be warned that mice reproduce quickly, so you can soon have thousands of them on your hands. The gameplay is nice but repetetive. However, the comic effects of the "Lump of Chernobyll" weapon add a lot to the overall fun. A nice game.
