UPDATE: The half-screen issue has been fixed. It was a problem with Firefox rendering CSS differently than Webkit. Sorry for the confusion!


Help guide a group of white blood cells through an endless, clotted artery of pain and despair! Yay!

1. Tap/Click to send a pulse to move your white blood cells
2. You regenerate cells over time.
3. Avoid blood clots.

Made for the Global Game Jam 13: "Sound of a Heartbeat".

The game's broken.

Not because it's loading, but it has slow FPS in zoom out and I was simply able to get a white blood cell outside the vessel and do whatever I wished.

If I were to do so I could possibly let the cell count rise indefinitely, but that would probably kill my PC.

No points, broken game.

Five stars for both the game play and the fact that it works.

Try Google Chrome instead, it's a neater browser anyway:
