improvement ideas
Ideas:
*You should old stop sounds playing when you start a new one.
*Maybe have the sounds triggered in a more futurama way?
(ie, get a screenshot of the controlls to their ship, or other devices featured in the program, then making the buttons on the device make sounds)
You could replace pages 1+2+3 with these pictures.
*Maybe some basic visualisation/easter eggs?
(some sounds trigger animated events).
Dosnt mater how small, but something like that will make this more amusing.
If your going to specilise in sound boards, you should try to make them more then just "button=sound".
