I started writing my first computer game when I was 16. It was a puzzle game where you had to move bricks and make them disappear. A couple of friends joined the project, and soon the game featured a detailed concept, graphics, levels, and even a penguin mascot (the Linux mascot was yet to be invented). Only the program had to be written. At that time, I was coding in the assembler language on a C64 computer. At first, programming was easy.
