A2K
===

1) Mechanics of the game
------------------------

The objective of the game is to move tiles around the board
using the four directional buttons. When a tile hits against
a tile with a similar value, one of the tiles is promoted to
the next letter up, and the other tile disappears.

A hits A: one tile becomes B and one tile vanishes
B + B: C
C + C: D... and so on

This version of the puzzle calculates all the values in each
row simultaneously (*):

For example, the following combinations are possible

B + B = C
A + A + B = C
A + A + A + A = C

The game is won once you reach all the way up to K

The game is lost is all the positions in the board are filled (*)

If a tile hits another with a different value, both stay in their
positions.

If a tile can be moved in the chosen direction, the tile will
slide until it hits another tile, or the edge of the board.

A random tile is placed on the board every time a directional button
is pressed -even if there is no movement on the board. (*)

(*) Other versions of 2048 may not include these rules - particularly
the "board is full" rule. 

Bottom line: don't let the board get full. Ever. A board full (even
with the same tile) will end the game

2) Controls
-----------

Directional buttons: slide tiles in a chosen direction
B-button: reset game
C-button: exit game and flash LOADER.HEX

3) Version
----------

This is a BETA version of A2K. No further features are planned for
A2K - it was created as a simple project to grasp the foundations
of Gamebuino programming over a few days.

You are free to add or modify the code as long as you abide by the
terms of the licence.
