Mini Transport

Bored at home during the Spring Festival, I made a small game to entertain myself.
This game is very simple to start, drag and drop lines between each node to establish a connection, in order to transport the product of one node to another node, produce a new product or sell it.
In this process, pay attention to the use of limited human resources to increase the speed of certain pipelines in order to achieve load balancing throughout the industry chain. And be careful not to let yourself go bankrupt with rising maintenance fees.
