Walk along the dark corridors, complete the tasks collecting precious stones. All you have is a lantern which lightens your way. It is very easy to get lost in the walls labyrinth and fail to complete the task before the time is up. For the money you earned you can buy upgrades for your lantern, weapons (which you will need in the next levels) and other useful things. You can buy these things after you finish a level. The game is rather difficult as it requires fast and precise walking according to the map. You need to collect keys and find doors all the time and this makes the task even more complicated.
In case you fail to complete the level – you will have to start the game from the very beginning!
