You don't have to collect all the treasure to complete a level, but collecting treasure also gives a time bonus which will be invaluable on later levels. I don't make up the rules! There are secret passages to help you get around the maze.
If you drop a stick of dynamite on them, or they run over it, they are destroyed (but more will come!) Note you can only shine the torch left and right, and you can only drop one stick of dynamite at a time, which takes up to 4 seconds to detonate. If you shine the torch at the snakes, they are dazzled for a few seconds allowing you to sneak past them. Unfortunately, the Pharaoh's treasure is guarded by deadly snakes! Luckily, you have at your disposal a torch and an unlimited supply of dynamite. You can collect treasure, and find keys to open the locked doors to access further chambers. You are an adventurer exploring a long lost Egyptian tomb. Transport yourself back to 1984 for this home computer classic for the BBC B Micro, originally published by H-Soft.
