This is just a small update for "spcinvdr" by Kevin Williams

Hopefully the following is now true.

The "s" key now toggles the sound on and off while playing.
The program no longer asks for a delay depending on computer speed and instead is on a timer.
Number of lives left is shown in the top right hand corner.
A final wave (wave 17) of aliens has been added.


If I make any future amendments to this game then it will probably be to introduce soundblaster sounds to it.
