The game was a bit smoother when it jumped you right in: I don't like starting at the complex settings screen. I think it should start with some default settings already going, very simple.
But there should be a settings tab that can be opened. Here you adjust the basics, and have the performance bar. Also a "HELP" tab that displays all those diagrams. That would help smooth things a lot.
If those sliders changed things real time - modified the settings as they were running on the left - that would be cool. Don't know how feasible that is.
The music is pretty greating, for a game like this, I think something more low-key would be nice. Get something much smoother, or start with the music off by default I think.
