You play the game as a single bit of computer memory. You can invade other bytes around you and thus modify their values. The game features various types of puzzles: With ability to XOR into adjacent bytes, you can navigate your way through existing data in the memory. The game automatically marks the bytes you cannot go through without getting yourself overwritten and prevents you entering those. Both binary and ASCII views are available, which you can utilize to find an open path for a particular puzzle. Various programs run on the computer you are trying to escape from. The game includes a disassembler showing you the assembly language corresponding to the machine code that is being executed. Don’t worry if you don’t know any Assembly. There are only a handful of CPU instructions and they are introduced gradually as you complete the puzzles. Reading the assembly code, you can track the program logic, see which parts of RAM it reads and writes to and manipulate data in those locations to get the program to do what you want. Having some programming knowledge makes the game easier, but it isn’t required. All the elements required to solve the puzzles are explained in the game. As long as you like doing basic math, you should be able to figure it out. That being said, it isn’t a game for general population. It’s meant for players who are interested in computer internals, assembly and machine languages and programming.
