My only complaint is that the music is way too loud. Takes away from the story. Hopefully there is a setting added soon that will allow us to adjust that. ### 3/5 — Has a few issues *2017-02-16, version 1.0* We are so excited to have a follow-up to Goodnight Lad, and expect that the few bugs with this app will be fixed soon. We can't get the app to load on our iPad Pro - it keeps crashing but works on the iPhone. However, every time we get to the part in the story where the bed grows in size, the app crashes. I bet this is coming soon, but the ability to turn music off would be great. ## Frequently asked questions about Marvelous Machines ### What is Marvelous Machines?
