I don't see a download button for the Zika app. (Loved Orbital Cow BTW)
Glad you enjoyed it! I've been wrapped up so much with the MSI jam that i've not had a lot of time for fun projects like Orbital Cow 2 :D Have a lot of catching up to do!
That said, not sure how or why the Zika file set was set to disabled for the download. Didn't receive a notice about anything. I've unhid the download, but fair warning: lower expectations. Super low. Then lower then another three feet :)
