Wonderful mining game!!!
i think would be nice to put levels:
-normal
-hard double damage, more difficult to get resources(less percentage and lower level in the ground(you need to get injuried if you want some lava :) ) and without tutorial
-insane(hard mode with you die and you need to begin the game :) )
like somebody say would be nice hotkeys for dinamite , teleport....
thanks for beautiful game, i finished one time and i begin now the second time :)
