After spending some time reworking mountainsides into castles and digging tunnels to the Oort version of China (I assume that the Chinese players are digging tunnels to the Oort version of Steubenville, Ohio), I’ve noticed that my fingers get very tired as I pickaxe my way through the rock. I’ve also not been able to find an auto-run key, which amounts to the same kind of repetitive stress injury as digging. In the final release it would be useful to have keys that allow auto-run and auto-dig to the limit of the reach of the tool involved (about 10 blocks, as near as I can tell).
