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".

Nice work for an HTML 5 Game, it's actually pretty good and yet it's fun although you may wanna add more levels then just some blood stream with clots and all. Also, You may need to add some more enemies and all! Besides, that you did pretty decent I could tell you that much! :)
