LOL FOUND THE GLITCH :(
Here's the deal. Almost all your data is saved. What isn't saved is the number of total events you've undertaken. I can implement a short algorithm to calculate it so don't worry about if your Total Events box is wrong. If the Level and Quests are correct, your data is fine. If you're starting again from the start, I have no idea what's going on.
I absolutely hate the lag, I turned down the uality and it's still there.
There really needs to be a way to switch of all the fanciful stuff, like the random guy below, or the random circles that appear when you hit a note, or even the song itself.
