When we boot we’re in the Minecraft game. Read the to load Scratch need to get to the Raspberry menu. How do I get to that menu?
Easiest way is to plug in a ush keyboard and press ctrl-alt-delete and move the mouse to the top of the screen and you will see the menu.
I’ve suggest the Piper team add a button to shutdown The Piper/MindCraft program and leave you in the desktop. Hopefully it will come in the next release
