King Palace Escape

Imagine in this game you are a burglar who have been planning to steal a precious sword from a museum which was converted from a castle which was the habitat of a king in the medieval ages. It was heavily secured because the sword belonged to the king and it was used in several battles during the history. Hence you had to devise a painstaking plan of escape after you managed to obtain the item. When it was ready and thorough you set out to fulfil the plan. On a cold night you sneaked into the building and put the unprecedented item to your backpack. The only possible way out was through the roof because the entrance was guarded all night long. Find hidden objects and fit them together to make your way away unnoticed.
