1. I tried to increase the saturation of Stella's palette to try to improve the colors.
2. Flash doesn't have a sound synthesizer, nothing I can do about the fact that it would call the audio playback routine 1/3 as many times as before.
3. I think I screwed this part up too. I place the ball in the top row (and same X coordinate) when you return to the main menu, so UP gets the character to walk in the select screen, but only if the character was centered on the screen before returning to the select screen.
