DubiousMerit: Thanks , will take note on it, and thanks for the comment ^^.
Phreaky: The clue for the code is from the map.
thundadowq: yes you can use the pick axe to escape, but it may take very long time, before that you may froze to dead xD, actually you have your point but if like that it will become "action" game, or maybe not even a game >.<
"Use your item to integration with the scene", for example: drag the key to the door to let it open... and you need to find two key in the game, one is for the box another one is for door... sorry for my bad explanation ...
Open the inventory by just click the inventory background of the item and then drag the item to the inventory that you open to combine it, but not all item can combine together
