Hello. I have a suggestion to add to the game a dynamite (or other explosives). Dynamite will be useful to faster mining, but it will be difficult to create. I think that the add sulfur and carbon for extraction and a new workbench for mixing these raw materials will be a good solution. After the merger of sulfur and coal would get gunpowder. To do dynamite, will need gunpowder and dirt or stone. Dynamite will explode after 5 seconds (?) after placing dynamite.
P.S. Sorry for my English
