The more expensive explosives are not worth the price. You actually make the most profit using the cheapest bombs. Around the $250/explosive mark is probably the best speed/profit ratio. The most expensive stuff is a rip off.
Game gets boring after a while, it needs more variety toward the end of the game.
I got really addicted to this for a long time but still could use a little something though like maybe extra workers or something like that that gather gold nearby but great game.
Mining Games are awesome!
I wish this had medals to unlock, but apart from that a really great game. A good mix of skill and strategy
Amazing Game! MAKE MORE LIKE THIS!
Great game, would be even better, if there would be a small descripion for the explosives and maybe a more detailed data on the upgrades. for example: refinery upgarde 2: +5% gold. but even without it its really fun to play
