Hey,
thanks for the review! Yeah an indictor or at least a clearer warning, that you die without stamina, would have been good. It only is written in the helptext I think. :) Regarding the Mining. You get always ore. If you are perfect you get the full amount. If not just half, but always at least one. If you venture deeper the ore in one spot ramps up really fast, and with a faster pickaxe your limitation is really only the load and you want the backpack and stuff.
But thanks for all the hints nevertheless. Glad you enjoyed it!
