Click green flag to start. Click on the ore or press space to earn items, gems and random rewards. You can sell item with "Sell here" for written price after waiting selling cooldown. You rank up by pressing rank up. That increases money you gain. You need about 184.85B to rank up from A to Z. When you prestige you rank resets including money you get, so you should save at least 185B before prestiging.
If you find any bug please share it in comments, I will try to repair it. Nickname for better comapring players will be added when it will be possible.
