/* global vars explanation:
a,b,c - preset vars
A - shortcut to fillStyle prop
f -player color
g - game mode (34x34 or 50X50)
h - enemy color
m - victory (victory text)
n - field side length
o - diamond side length
p = n-1 - to save couple of bytes
d = n+3 for the same reason
q - two-dimensional array (play field)
r - number of diamonds, that belong to player/enemy (after executing v() function)
s - main function (start/restart/keypress events)
v - recursive function, that "paints" diamonds to new color
i,j,k,l,x,y,z - some local vars, which function changes depending on context
