Stop light app crash

I was thinking this game would be more fun but I found it to be a little hard to use because the app keeps crashing on me when Im playing so it does need an update also when your tapping the lights it takes a little long for the light to Change so the cars start to crash on me and I cant make it to the next level please fix this, overall it would be fun if it worked right I was being hopeful for my first 3D app
