Unfortunately, we've got a little held up with making the "official" save game converter for VVVVVV (for converting 1.2 save games to the new 2.0 format), so I thought it would be a good idea to highlight
ConVVVVVVerter, an unofficial save converter made by Steam forum member SupSuper! It's very easy to use and works perfectly on both Windows and Mac, so I totally recommend using it if you're sick on waiting for us to sort it out.
