The game is called Deep Town: Idle Tycoon. You start with a few idle mines, some tools and maybe a few bots. With these, you can start producing your first stuff. After a while, you will be able to produce some of your own things. But you need more, and faster.

With new tools, more idle mines and more bots, you will be able to produce more of your own stuff, thus, more money. With the money, you can buy new tools, idle mines and bots. It is not easy to get the money, but you have a couple of ideas how to do it. The first idea is to collect as many coins as possible. Another idea is to sell all your tools to someone else. And another one is to make a couple of products with tools and sell them for cash.
