Each level contains multiple rooms with one or more treasure chests.
The chests hold special idols that are required to open up more areas of the tomb so search high and low for these chests.
Some are a little tricky to obtain, but dont worry since not all chests are required to complete the game.
Remember, you can always return to a tricky level later.
