Mental Kombat

Each player has their own color.
You have to connect tiles of your color vertically or horizontally.
You can move every tile of every color, this means that you could connect a row of tiles of your opponent's color if you don't move carefully enough.
To prevent deadlock situations you can't undo the last move.
If you complete a row of your stones your opponent will lose energy.
If one player runs out of energy the battle is over.
