Not really a full-blown demake, but a friend of mine is working on a mod of a different game and one of the classes is inspired by VVVVVV.
Video demonstration (complete with VVVVVV music)
Funny story, the mod is of a demake. So we've got a fan-made homage using a fan-made demake of Team Fortress 2
If anyone's curious, I'm one of the programmers working on the base demake that this demake is based off of. Cue the Inception jokes.
