Miners spend much time under the ground, because this is their main income. There, they can and do hack. For example, two of your hero found a gold mine, about which no one knows, and go on to collect gold and gems. All the actions they have to perform together. For example, to get to the platform one needs to keep the lever, and the second climb, the one that got clicks and misses the second. Thus you will be able to quickly collect all the treasure and become rich enough.
