Sokoban Puzzle Dragons description

Sokoban is a logic game where your task is to move boxes into proper place in the warehouse. This sokoban is with dragons instead of boxes :-) If you need a back-story: it is so cold in the dungeon that dragons are freezing! No wonder they are blue.. Your task is to move them to the fireplace to keep them warm. This game can really stretch your brain muscle. Best of all, no angry birds died during developing this game ;).
