• Level unlock: To (temporary) unlock all 150 levels, first collect all the gold on level 1.  Instead of using the escape ladder, dig a hole in upper-left tile of the screen and jump through.  Next, quickly dig a hole in the tile you just landed on and repeat this until you dig a hole in the lower-left tile of the screen.  Now, jump into this hole (while the upper-left tile is also still a hole) and you'll die immediately and be brought back to the menu where you'll see that all 150 levels are unlocked.  You have to dig quickly to be able to unlock them.  Note the unlocking is only temporary while your session lasts, and while it does, your score won't increase and your progress won't be stored to SaveKey.  {Dion Olsthoorn}
