Tips and Tricks
As you dig, you'll come across crystals that will replenish either your health or tech (which you need to use bombs and other high-tech tools).
Keep an eye for gold blocks as well.
Avoid enemies whenever you can. Stay out of their way, or use a bomb to get rid of them.
Spiders don't provide much of a threat unless you run into them, but mummies will chase you around.
Once you accumulate enough gold, you can put together two items and create a more effective one. If you forge two Hammers together you'll create a powerful pick, which is capable of generating energy for both your health and tech etc.
Traps are available later on in the game, and you can use these along with your bombs and tools to trap enemies and earn some gold as a result. However, we advise you to be careful with these. Setting a bomb off in the wrong place could leave you surrounded by rock.
