How to Play

"Hi hero! You're a healthy red blood cell. Move with your finger, mouse, or the arrows. Sweep up every Oxygen Orb and Bead of Courage to clear the level — and learn a little about blood along the way!"

• 
  Oxygen Orbs — collect them all to finish the level. Red blood cells carry oxygen everywhere.
• 
  Beads of Courage — each one pops a Did-You-Know fact. Kids use beads to tell their treatment story.
• 
  Blood Donor Power-Up — go SUPERCHARGED: briefly protected and you can rescue cells by touching gremlins.
• 
  Lizzy's Loot — hidden treasure: big bonus + a surprise fact.
• 
  DBA Gremlins — Diamond Blackfan Anemia challenges. Avoid them or you lose a life (unless supercharged).
