Hm… the first bit has me a tad confused; what machine are you talking about? I may just be missing something (has been known to happen), but I don’t see another machine really mentioned in this.
That bump aside, everything else works very well. I especially liked the rather jerky pacing, it felt very real for this sort of situation.
Thanks for entering!

@g2, thanks. It was my attempt to express how strong someone or thing would have to be to scar the walls. As in, a human couldn’t be so strong. In hindsight, it was a bit cryptic and out of place with out further explanation.
