_TITLE "Invaders b0_4_1" 'Bplus started 2019-07-27 inspired by Ken's fun program series
' 2019-07-29 b0_3 from feed back fix game ending with big "Game Over" sign and delay before Top Ten.
' Show score to compare with Top Ten Numbers.
' Change the way hits are calculated, use method that avoids distance function or ABS.
' Change TopTen sub to TopTenGoAgain$ function to also get Play Again reply.
' OK let's start charging for bullets! 1 point per... and do a hit % to reward skillful shooting
' change BEEPs to SOUNDS, add more to report, Game Over signals end of game, TopTen does go again also.
' 2019-07-31 Rework the Top Ten screen using Text sub routine that I want to demo in "another one for the Toolbox."
' This new TopTen function now uses inputBox$ which added a ton of lines to the program!
