Gem Miner Dig Deeper Extreme Difficulty (Part 5 - Upgrading a Lantern)

This video shows how to upgrade your small lantern into a medium lantern. Now once you pass the iron level, it gets very serious. There are a lot of crevasses in this difficulty (lower difficulties have fewer crevasses), and you need to save ladders to get back up. So I keep 5 ladders just in case I get stuck. You can only have 1 survival kit, and you have to use it wisely. Once you ran out of stamina, it's over (not game over though). Also, if you are under the bottom of the crevasse or the ground level, place a support because if you are going up, the rock can instantly kill you if you don't place it. You will encounter irons, and they appear after the coal level. They sell $25.
