Magnetic Blob Tumor Run

Guide a tiny iron-coated medicine blob through the bloodstream. The vessel gets faster and narrower. Touch the edges and the mission fails. Reach the tumor, flip the magnetic field, and release the medicine.

how to play

Stay inside the bloodstream.

  1. Move with arrow keys, W/S, touch, mouse, or the on-screen controls.
  2. Avoid the vessel walls. If the blob touches an edge, the mission fails.
  3. Collect medicine charges as you travel. The path narrows as distance increases.
  4. At the tumor, press Space, E, or Release Medicine to flip the magnetic field and attack.
  5. On mobile, use the Up/Down buttons and tap the Release button when the tumor fight starts.

This is a fictional educational game inspired by magnetically guided drug delivery. It is for coding practice and entertainment, not medical advice.

inspiration

What inspired this game?

The game is inspired by a Veritasium Short about a tiny magnetic gelatin-and-iron-oxide blob that could be guided through blood vessels toward a brain tumor. The video idea became a simple coding challenge: steer the blob precisely, avoid vessel walls, collect medicine charges, then release the drug directly at the tumor.

This game is fictional, simplified, and made for learning web coding. It is not medical advice.
