New hexagonal map

The main game map has been updated. Hexagonal tiles are  the most obvious change, but it plays differently as well. When you remove a tile randomly selected hexagons  around it disappear as well, depending on the number in the tile, making the process a mixture of luck and thinking.

There are also new  tilemap graphics demarcating the rooms difficulty. These new room are opened by looking for special big keys.

Small tweaks and polish are all around the game as well as some more hidden secrets as well.

If you play the demo let me know what you think ;)
