In Mystic Mine you control a gold car inside a mine. The objective of the
game is to get as many points as possible by collecting coins, diamonds, gold
blocks, etc. The levels feature an Escher like optical illusion, so it’s
possible to keep going down all the time.

The game can be played single player or multiplayer with up to 6 people on 1
keyboard. It also features a single-switch gameplay, so you control everything
with only one button. This button switches the track crossings in front or
your gold car. The difficulty of each level adapts dynamically to how good you
play.
