Markus Wildi and Marius Wey had programmed their game Muri (1987) for the Armstrad CPC 464 computer. The listing of the game is described in German and printed in the magazine Happy Computer 12/87 as the "Listing of the Month". The editors of Happy Computer praised the game as a “a real treat for Schneider fans”. They further explained, that Wildli and Wey wrote the game as 15 year old teenagers. According to the description, they received 3000 DM for the listing. It is further indicated, that the game is named after the Swiss city Muri, possibly derived from the word „mur“, which means wall in Swiss German. Refering to the wall of bricks in the game.

This means, Muri is a breakout game, that is nicely designed and comes with some extras. You play the game using the paddle visible at the bottom of the screen. The key moves the paddle to the left, the hyphen key next to SHIFT moves it to the right, and SPACE acts as the fire button and also starts each new round. The paddle must return the incoming ball to the playing field every time. As an extra, during the game, a “barrel” occasionally falls from the top of the screen, which significantly affects your paddle.

The game comes with good sound and intuitive navigation. An editor and a two-player mode complete the game. The falling barrels have different colors and change the function of the paddle. A yellow barrel gives you an extra life. Blue barrels make the paddle bigger, and green ones (which are extra tricky) reverse the controls. Red opens the way to the next level, and gray turns the paddle into a double-cannon.
