You find an old computer, and you turn it on, only to discover that it is inhabited by a digital companion named LITA, designed to pass on knowledge that was forgotten by humanity. LITA's mission is to guide you through a series of challenges that explore the basic of low-level programming, focusing on how computer memory works. Starting with simple concepts like variables and their representation in memory and slowly move to more advanced concepts such as pointers and memory manipulation. But LITA isn't just an instructor. As you go through, you will undertands why she was created and that not everything happens by chance. Through visual programming, connecting instruction blocks, you will be able to create small programs and visualize their execution while watching, in real time, the changes in memory. No prior programming knowledge is required, just curiosity and a love of solving puzzles.
