Without Bowen's tutorials I'd be mostly lost on the game. I was lukewarm toward the game until the 1.6 code.
The biggest problem with song selection is it shows you the first shot in a mode, but then you're supposed to shoot other shots after you make the first one to complete the mode and score points. It's somewhat pointless and steers the player in the wrong direction. The color LEDs helped a bit. But I still see players shooting the same shot over and over and wondering why nothing is happening. Imagine if in Tron you lowered the recognizer and shot the disc ONCE, and then you were supposed to shoot everything else but the disc in order to activate disc multi.
