Description of the implementation

Using only 0x00 to optimize the memory usage.
Using only unsigned integer 8 bit (uint8_t).
Implementing the LCD as points (x, y). So the game 20*2 means that the first row from point (0, 0) to (0, 19) and the second row from (1, 0) to (1, 19).
The code is well organized, divided into H files, commented.
Small memory use without using any extra memory.
