Muku no Yuubinya-san

Released in January 1984 by Compack, Muku no Yuubin-ya-san is a PC-8801 action game where players control a puppy named Muku as he attempts to deliver mail. Spanning 100 levels, the game is characterized by its maze-like town layouts and puzzle elements that require players to manipulate "blue walls" to clear a path. Despite the charming character design, it is a surprisingly deep title that demands strategic thinking, as careless route planning can easily result in being blocked off. It remains a memorable example of the creative ingenuity found in the PC gaming market of that era.

In this action game, a lovable puppy named Muku takes on the role of a postman. Players control Muku as he races through a complex, maze-like town to deliver mail to its destination. Various gimmicks, such as moving blue walls, stand in his way, and players must carefully consider their route to avoid being trapped. Across 100 challenging stages, you must use strategic thinking to ensure every delivery is a success.
