Catrap

Catrap is a puzzle game. The player directs the avatar, an anthropomorphic cat, to navigate a room while clearing obstacles and kicking monsters and ghosts off the screen. Once the player has knocked all of the enemies off the screen, they advance to the next level. Advancement grows difficult for the player as increasingly intricate obstacles are presented to complicate the process of overcoming all of the monsters and ghosts.

The game encourages trial and error. A player may try one combination of manoeuvres by moving the obstacle in one direction, then they may find themselves trapped. The player can hit the 'A'-button to reverse their movements and try again in a different way until they find the solution that enables them to access all of the enemies and knock them off the screen. Trial and error make up a large portion of the game.

The game concept was originally created in 1985 on a MZ-700 home computer by Yutaka Isokawa. MZ Publications" as a type-in program. The popularity of the game caused it to be picked up for Game Boy conversion in 1990. In the Game Boy version there is a nod to the MZ-700 version, the layout of round 77 is a big M and Z.

In 2004 it was released for I-mode mobile phones as Pitmania and Pitmania 2, with graphics more similar to the original MZ700 game. Pitmania 1 Infinite was released in 2007, which had improved and more colorful graphics. A version was released for the Nintendo 3DS as part of the Virtual Console service in October 2011 and for DSiWare in December 2011. In 2012 the game community restored a faithful as possible Sharp MZ-700 version from the available source code variants.
