Help with my game please

jeltheiosdeveloper

In the game I am working on my character moves from side to side using accellormeter (thank you Tshirtbooth for lovely tutorial on setting that up) and I have a hidden wall actor on the sides and on the bottom so it will not go beyond that. it bounces of . However in testing sometimes although not very often my character starts spinning and goes up. How can I stop this from happening. Maybe something along the lines of a min and Max X value (like a slider)
Also how do I make a pop up menu. Like when they press a button instead of going to a new scene it pauses the game and a menu pops up which has options for changing volume etc
