I also making indie Games and the discovery problem is huge. Now I've come to the conclusion that the only way to make my games visible is to pay for advertisement and try to be featured on game reviews site. Nevertheless, I found it quite hard to believe how you got 50k installs with only 1100$. How come? we are not getting more than 2000 installs with that same amount.
