High load memory for low phones made it crashed when switching screens

You might eliminate the Blocks that play a sound file or place the the Sound Play block in the in the Initialize event handler of the Screen you use the Buttons to move to. 
or use shorter sound files.
Also, avoid the animated gif; that uses lots of memory.
Does any of those ideas let you avoid the crash.
