Bone Marrow is a dark fantasy version of the popular math puzzle game 2048. You have to fight against a computer opponent, combining weapons and armor. The main goal is to bring the enemy's health to zero before he does the same to the main character. Each element on the square battlefield has its own special effect, and therefore the game has gone quite far from the original concept of “2048” and will give a bunch of new emotions to fans of the classic puzzle.
