Hi,
According to the FAQ:
What is Hardware Tycoon made in?
Hardware Tycoon is an HTML5 game made using Scirra’s Construct 2. Desktop versions run on nw.js.
I don't have any real advice on game engines, it always depends on the project and your proficiency in the given engine. Construct 2 has been unsupported for a couple of years now, but Construct 3 seems decent enough if what you need is a tool to make a simple game quick.
