So my first app - Quiz Champion (https://play.google.com/store/apps/details?id=com.digitaltreegames.quizgame) is live on Google Play.
Whilst it does not have many downloads, as it has not yet crossed the 5k mark, I am providing the information to those who are in a similar phase as me. I hope you find it useful and also provide me with some feedback:
Thanks for your feedback. I am not a designer and no one else has mentioned this to me before you, but I do see your point.
I paid $75 for the art of the buttons and achievements But I have been told that fiverr is a better place for art.
