Confused, but great Game! – Idle Heroes - Idle Games Review

I kept ignoring the ads for this game and one day I said what the hell im just gonna try it. So I Tried it and it was GREAT the only thing is, is that they advertised it differently as shown, but still great game! P.s: how can you combine heroes to become stronger? E.g: a ins Star becomes a two star, a two star combines and becomes a three star... ect.
