You play as a mouse who has to move blocks in order to trap all the cats on each level. Once you have trapped them to the point where they can't move they then turn to cheese and so on until you lose all of your lives. Any help would be appreciated.
The game is "Rodent's Revenge" and was one of a handful of games that were included in Microsoft's Best of Entertainment pack released for Windows 95. Personally, I preferred "Chip's Challenge."
