What do the screens say after you are set free?

Riffing off of Resposta de Valorum, guru meditation is a reference to a famous Amiga error. From The New Hacker's Dictionary:

Amiga equivalent of panic in Unix (sometimes just called a guru or guru event). When the system crashes, a cryptic message of the form “GURU MEDITATION #XXXXXXXX.YYYYYYYY” may appear, indicating what the problem was. An Amiga guru can figure things out from the numbers. Sometimes a guru event must be followed by a Vulcan nerve pinch.This term is (no surprise) an in-joke from the earliest days of the Amiga. An earlier product of the Amiga corporation was a device called a ‘Joyboard’ which was basically a plastic board built onto a joystick-like device; it was sold with a skiing game cartridge for the Atari game machine. It is said that whenever the prototype OS crashed, the system programmer responsible would calm down by concentrating on a solution while sitting cross-legged on a Joyboard trying to keep the board in balance. This position resembled that of a meditating guru. Sadly, the joke was removed fairly early on (but there's a well-known patch to restore it in more recent versions).

I managed to freeze-frame it on this "ending" video

As @Fuzzyboots has pointed out in his answer, the words relate to an (old) easter egg error message used on Commodore Amiga computers. In this instance, a software failure that would require a reboot, the numbers 48454C50 spelling out "ajudar" in ASCII code, which signifies a fatal error that the computer can't diagnose.

I'm not sure what the ? is. Possibly a block ▊ or a hash #
