20 March 2003
+ Added "restore colors" at exit time
+ Removed extra spaces from strings... saves 100 bytes
+ Lots of infrastructute to compress data segment... saves 2k
+ Change all the cool "bt/btr/bts/btc" op-codes to equivelant
  or/and/xor.  The former was cool, but slightly longer.  Sad, sad.
+ Found if I remove ".data" the text+data segments are merged saving
  3k.  Cool, especially as I don't write to the data segment at all anymore.
+ Use sstrip.  There are random file lengths that either "strip" or
  "sstrip" don't handle well.  May have to pad things out in the end
  
21 March 2003
+ convert "get_char" and "get_a_char" to return status in the carry flag.
+ Much optimization.  See "optimization" file.
+ Now under 8k ;)

23 March 2003
+ Extensive play-testing to make sure optimization didn't break game.
+ Fix "sstrip" program so it puts the bss on the proper boundry.
  Hope this isn't "as" version specific.
+ Game balancing.  Moved up to 6 enemies.  Slight shifts in
  game engine constants.
+ Fix problem where enemies get stuck at level 4.  As a result
  level 7 never ends, as we do tricks where we use level*16 and
  over 7 that overflows to negative.
+ Play tested.  Seems ok.  Release 0.32!
