how to make a mobile game

I want to know how to make a mobile game. I have tried to make a side scroller but it didn’t work I wanted to add simple obstacles like fire so if the guy collided with it he would die. I used the preloaded unity mobile side scroller pack Can any one help I have tried. thank you in advanced

You may want to take a step back and go through some simple examples first, before diving straight into mobile development. Unity has made some excellent tutorial videos that will give you a good grasp of the basics and give you the background you need to dig into the side scroller pack.
