Mouse Trap

When Pac-Man arrived on the arcade scene, and literally took it over, the arcade industry stopped and took notice. So it wasn't long before imitations arrived on the scene. Three such imitations were Lady Bug, Lock'n'Chase, and Mouse Trap. Interestingly, all three games offer the player with a mechanism to alter the layout of the maze.

Mouse Trap was an arcade game developed by Exidy in 1981. It borrowed heavily from the Pac-Man theme, but it gave the most control over the maze layout than any other imitator. Mouse Trap pits you in the role of a mouse who is trying desperately to collect cheese in a maze full of cats. Mouse Trap provided the player with three buttons, each one a different color, that corresponded to the three different colored doors on the screen. When you hit a certain color button, the doors on the screen of that color move and rearrange the maze layout. You can use this to open a getaway path, or escape from a chasing cat. Additionally, you can hold on to the power-ups, which come in the form of dog-bones, and utilize them whenever you prefer, instead of the moment you collect them. The dog-bones temporarily transform you from a cat fearing mouse, to a cat stomping dog.

Mouse Trap gave player's a greater sense of power over their fate, and when Coleco was hunting for licenses that would compliment its ColecoVision system, they saw Mouse Trap (as well as Lady Bug) as good competition to Atari's Ms. Pac-Man. Coleco proceeded to develop and manufacture the game for their own system, as well as port it to Intellivision, and to the Atari 2600 which naturally saw a rather crippled conversion of the game due to the lack of available button inputs. While the ColecoVision and Intellivision relied on the number pads attached to the controllers, the Atari 2600 version distinguished between long and short button presses.

Story
It's not easy being a mouse that loves cheese. Especially when your greatest source of cheese is contained in the alleys where the alley cats roam. But your no ordinary mouse. You have abilities. Like the ability to open and close the many doors found throughout the alley. And the more extraordinary ability to transform into a dog by eating dog bones. If that weren't enough, there's also the giant hawk to watch out for.

Gameplay summary

 * You control the mouse through the maze. Your goal is to eat every piece of cheese in the maze.
 * You must avoid contact with all of the cats, as well as the hawk. If they touch you, you will lose a life.
 * You can press one of the three colored buttons at any time to move the corresponding colored doors in the maze.
 * In addition to bits of cheese, there are dog bones in each corner. If you collect the bones, they are added to your bone storage.
 * You can activate a dog bone at any time as long as you have one in storage. You will turn into a dog for a while, during which you can "eat" the cats for points.
 * If the hawk is out, you can confuse it by entering the "IN" box in the center of the screen. Entering "IN" sends you randomly to one of the corners of the maze.
 * Throughout the game, bonus objects are scattered around the stage. The more you collect per stage, the more they are worth.
