This is a flood-it clone inspired by the game Ink Spill from the book "Making Games with Python & Pygame". This game and also some of the others that I have already done and published here are part of a personal challenge which consists in doing clones of these games.
In order to win you have to flood the entire board with one color within a certain number of moves. You can do a flood fill on the tip left tile, changing the color of any adjacent tiles of the same color.
