How to Play Yoyo Hero
Control the Yo-Yo
Move your mouse to control the yo-yo position. The yo-yo follows your cursor with realistic rope physics and elastic behavior.
Destroy Bullets
Use the yo-yo to hit and destroy incoming bullets. Different bullet types have unique behaviors and point values. Gray bullets require 2 hits to destroy completely.
