Alternate unlock method for anyone who doesn't know:
After some time in the editor (around 15 minutes, I think), regardless of what you're doing (or not doing), a message pops up saying you get new stuff tomorrow. However, you can speed that up by placing enough objects. So save your level in progress, grab the block or coin tool, extend your goal to the right, then zoom the camera around while scribbling and you should get the notification that your new stuff arrived right when you run out of objects to place. Then use every new part/level theme/whatever (clear every red !) and reload your save, then repeat. This worked every time for me.
