Yes your correct too! but I mean thats their decision... so they chose to have the game free on google play, app store, and steam. And earn from the websites where people download the game theirself. So I guess it's their loss but I mean most people have phones so I guess they decided to make it not free so they can earn a bit. While on steam it's free. But I mean we are just discussing how they get paid while it isn't our concern...so I guess I'm dropping the topic! Although replying to other comments is not bad. So you can interact with people on this website too.
