I’ve loved VVVVVV since it came out and took hold of my free time. I still have to beat Veni, Vedi, Vici…
I’ve wanted to play Pushing Onwards forever. I chose UnofficialSoundtrack‘s arrangement. Sheet music available for free: http://dl.dropbox.com/u/23040402/Pushing%20Onwards.pdf.
There is also a different version out there by arranger and musician Brent Kennedy. His version is more of an arrangement than a reduction – which this performance is. I will never have the dexterity that @UnofficialSoundtrack has. Have a listen to his performance… which is much cleaner and much more epic:
Pushing Onwards, along with the rest of the fantastic VVVVVV soundtrack was composed by Magnus Pålsson.
