Challenge - Firebug (C64)
 

As the story goes you're a firestarter, or secret agent, or something, and there's a burning building, which you can enter through the windows. Each window has a different level.
The goal is to grab the briefcas at every level.


I had this game on my Commodore 64, and never could finish any of the levels.


Here is the game:

Easily The Hardest Game Of All Time if you ask me.
