So I'm a complete idiot and forgot there were VVVVVV forums (and emailed Terry directly. May have not been the right thing to do, sorry!). 
Sadly, though, the new version of VVVVVV crashes on OS X 10.5.8 (which is not as old as 10.4.11) when it opens
I did a clean install to verify it wasn't an overwrite error. Same crash.
Below is the Apple bug report. Maybe someone can discern what is going on? Thaaaanks
