Hi,
not doing social media is a big mistake when you want to promote your game. I don't do social media for personal stuff, but I do have a twitter account for professional use. This is the way you put chances on your side for a post to go viral and attract players or be noticed by publishers, else your game has far less chance to become successful... I am not saying this is good, it's just how the market and people works unfortunatly.
Bye,
Jean
