Game: Rodent's Revenge (Windows 3.1)

Rodent's Revenge is a puzzle video game, created in 1991 by Christopher Lee Fraley. It was distributed with the Microsoft Entertainment Pack, which was included in early Windows systems. The player takes on the role of a mouse, with the objective being to trap cats by pushing blocks around, whilst avoiding obstacles. To win a level, the mouse must stay alive and trap all the cats using the movable blocks. Doing so changes the cats into cheese, which the mouse can eat for extra points. The player is given three lives before their game is over. There are 50 levels, which get increasingly harder, but the player is allowed to start playing at any level. The difficulty of each level is determined by several factors. Sink holes trap the mouse for a few seconds. Mouse traps will kill the mouse if it accidentally walks into one. Flying Balls of Yarn will kill the mouse on contact. The number of Movable Blocks will determine how difficult it is to trap the cats, while the Unmovable Blocks make it hard to move blocks around and hinder navigation. During each level a clock ticks away until it reaches a certain point, which is represented by a blue line. When this happens more cats are spawned into the level, making it more difficult, but also increasing the potential reward. After the new cats have spawned, the blue line moves further around the clock and it resumes ticking.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
