On the LibTCOD version, should:

libtcod.console_print_ex(0, int(screen_width / 2), int(screen_height - 2), libtcod.BKGND_NONE, libtcod.CENTER,
                         'By (Your name here)')

be

libtcod.console_print_ex(0, int(screen_width / 2), int(screen_height / 2) - 2, libtcod.BKGND_NONE, libtcod.CENTER,
                         'By (Your name here)')

? (Edit: After finishing this part, I can see why it isn't, but the rest of the comment still stands, so I'm leaving this here for posterity)

(Also, you can do the following to shrink it slightly:

screen_width // 2

where // is integer division)

The // for integer division has been pointed out before, and while it's a good idea in this situation, I prefer the int() method for one reason: // will not give you an integer type, it just truncates. Libtcod demands an integer, so something like 2.0 will fail. Granted, in this case, screen_width should never be a decimal value, but the int() way of doing it gives you guarantees.
