Maybe you could improve it opening/closing doors or even moving the exit. Anyway, I got an error on the second stage and I could not go on.
Did you try pressing z to reboot like it says?
It restarted and it hang again, sorry (I was expecting a surprise lol)
the error is fake. It’s intentionally in the game. The unexpected part is fake errors. If you just continue through the game it will make more sense.
