you can shave off more bytes by using string templates and whitespaces (\n and space) because the game doesnt recognize them as a character.
Ive seen someone writing a script that encoded itself completely in whitespaces making it about 30 bytes to the game.
This is an example what you could do:

  P = "red purple blue cyan green lime yellow orange 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 unlock open release" . split` ` ,
  z = "_..!
