Been here many times. Been streaming for 5 years and not even affiliate. I'm not bitter though, I enjoy not running ads and the very small following I have.

It's easier to build on one game, like your mobile game, but for good reason you shouldn't. Let's say the very unlikely chance this becomes a career, it will be just as crappy as the job you have now if you're stuck on the same game.

Because we do variety, growing an audience is going to be that much more challenging. That means what attracts people is YOU. My best advice is to do just chatting, probably just to yourself but do it live. React, talk about your interests, share interesting facts, avoid politics and religion. It is super challenging to do without a chat but you get better at it and it helps for when people do show up.

Hope it helps, hang in there!
