Spy Mouse

NOTE: This game is no longer as of 2015 available due to the fact the iOS 11 release got rid of all the 32-bit game

Spy Mouse is a popular removed good game.

Pros

 * Fun Gameplay
 * Power ups can be useful
 * Hard levels, more thinking!

Cons

 * Where the hell is the goddamn sequel
 * The bosses are easier than the actual levels (except the one from Ghost Town which is actually hard)
