If you suffer from Triskaidekaphobia (a morbid fear of the number 13), then rather do not play the game Trollface Quest 13. Why? Because just the number 13 is its symbol. Seventh part of the game Trollface Quest contains 13 levels and every of them is in a sign of bad luck. Is it just a coincidence? I do not think so. Try to go through all thirteen levels with minimal number of moves. Have fun.
