Thanks for playing, I'm a bit worried to hear about the precision being off - someone else had mentioned this too. Some of the notes are slightly off, I'll have to go through it and tweak it.
You mention it's only in some places, how often would you say it was occurring? Percentagewise? Any particular song had it bad or all of them? Was it a global sync issue, like your audio was always consistently behind?
I agree I could have made the other 2 locations strange too, but I ran out of ideas and wanted to give it more content!
And yes, I absolutely plan to take this one further :)
