DrinkBox is still working on the port, so details of the release plans are uncertain. The developer plans both PC and Mac versions; either the Mac version will hit soon after the Windows release, or they'll appear simultaneously. Mutant Blobs Attack will also support Steam Achievements. Naturally, it'll support features like "absorbing terrified people" and "otherworldly magnet powers."
Update: Drinkbox CEO Ryan McLean said the studio is "aiming" for a May or June release.
