From the developer:
Emerald Rush is a musical adventure game in which you need to solve puzzles and avoid dangers. You need to guide the game's hero through the gauntlet of abandoned mine levels, collecting emeralds, diamonds, and other valuables. Tectonic activity releases hot lava into the mine. Your heat-resistant jetpack suit will protect you, as long as you don't come in direct contact.
