UPDATE 2: If it's not loading, it might be because you're using IE9. Get Chrome:

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".

I wish I had time to take part in the Global Jam, but that's life. Anyhow, I like the execution on the theme. The gameplay is simple and challenging, and a thrill if you manage to get momentum going. I also like the morbid tone of this submission combined with the happy white blood cells.

Also seeing how it's HTML5, I'll throw down what browsers I used to play this in. All are on Windows 7 unless noted:
Google Chrome v24.0.1312.57 m (works perfectly)
Mozilla Firefox v18.0.1 (works perfectly)
Internet Explorer 64-bit Edition v9.08112.16421 (Stuck at loading screen reading 0%. And I've played through it on Chrome...about four times now)
Safari on iPad2 (won't load at all)
Chrome on Samsung Galaxy S III (Extremely poor performance. Terrible framerate, and seriously delayed controls.)
Firefox on Samsung Galaxy S III (Stuck on loading screen at about 95%.)

Now I'm not sure why it wouldn't work on IE9 or the iPad2, since I know that I've tried out my team's MolyJam game, which is HTML5, on IE on the Microsoft Surface and it worked, the iPad, while it worked, it had really poor performance.

That is all. Excellent work, especially in 48 hours.

Thanks for taking the time to do such a thorough cross-browser test!
I don't even have some of those devices to test on...

As for the iPad 2, it works fine on mine... although, I did upgrade it to iOS6.
I'm looking into why IE9 doesn't seem to work. As far as I can tell, it should have all the capabilities. So whyyyyyyy

Thanks again so much!
