  • EXE World: Triggered when the opponent hits astatic note. In this mode, yellow ring notes turnredand must beavoidedto prevent heavy damage.

To return to the Normal World, you must hit asquare static note. The more rings you’ve collected in the Normal World, the safer you'll be if you accidentally hit a red note in the EXE world. With zero rings, a single misstep could drain a large chunk of your health—so timing and strategy are key!
