Dungeon Crawler combinates Dominos to extend your path. 

Drag Dominos from your inventory onto the chain to reach the goal. Press [R] to rotate. 

## Idea (not fully implemted)

Attack by dragging a domino from your inventory on the enemy to gain new dominos. Rotate the domino to choose your attack/defense (upper eye is attack, lower eye is defense). You kill the enemy if your attack is larger than its defense. If your defense is lower than its attack, the difference is subtracted from your health.
