That’s blast radius, a level for Little Big Planet 2 created by Johnee. I found it by going to the community section, paging past the Cool Levels, Media Molecule Recommendations, and Text Search options to the More area. From there, I selected “highest rated ever” in the browse options. Blast radius appeared, and after a short loading time, I was inside a twin stick shooter with different weapons for blasting asteroids to get at the scoring crystals on the inside.
