TLDR: The display resolution on the official Raspberry Pi Display is too low for the Kano OS tutorial.
So I gave a 1080p display a shot this weekend. It worked! There is a bubble to pop on the right side of the display that’s not visible at the resolution of the official Raspberry Pi display. After that, the third bubble would also be too far to the right to click. Once I got my son through the tutorial he was excited to program Minecraft!
Unfortunately, when I moved the Pi back to the low resolution display, the programming environment added to Minecraft is fairly difficult to use, and the Kano dashboard interface doesn’t work, however the Classic Mode interface is very usable! Unfortunately, Classic appears to be missing some of the apps. I may end up purchasing a Kano Touch after all, but I still have a few experiments that I want to run. FYI after the tutorial completed and the Kano OS updated, the touch interface on the Raspberry Pi display works perfectly as well.
