 ## Implemented features
 + Debug functions - Contains simple but handy functions for debbuging. Can log single characters and can do assertions.
 + Random number generation - Uses Xorshift algorithm. Can generate a random number from 0 to 65534. Also has helper functions to generate a value from within a range or a random percentage.

 ### Why Xorshift algorithm for random generation?
 Xorshift is the easiest to implement especially because I've restricted myself to using 16-bit registers. Read more about it here: https://en.wikipedia.org/wiki/Xorshift
 
+### Why text-mode? Why not VGA?
+Because I like how text-mode graphics look and because it's easier to implement than VGA.
