you are not "right to assume so" if what you assume is incorrect. that's not how the phrase works.
A more accurate statement would be "you could be forgiven for assuming (assumption here)".
"any damage is repaired instantaneously by an unknown force."
We have mend-sedimen energy that does this exact thing.

"as any who have entered have ever left" makes zero sense. It should be something like: "as no one who has left has ever returned", but even that is irritatingly vague. what actually happens? do they just vanish? fall off into the void?
I get you want to be mysterious here, but there really isn't a reason this information would be unknown. one person simply watching another enter would solve that mystery.
A level having no entities is not strange. Plenty of levels don't have them, regardless of how easily they might survive in those levels.
Regardless, after stating that there are no entities, you immediately contradict yourself by saying "recent information may prove that there is at least one entity in the void."
this is a vague statement, that tells us nothing, and is never elaborated on. if such information exists….. why is it not presented? anywhere?
Missing entrance/exit section, though I'm going to assume you're waiting for the contest to end, in order to figure out what level number you end up with. fair enough.
If the entrance to the level is always the center, and you are most likely to find "travelling groups" there, why are they called "travelling groups"? they haven't gone anywhere!
aight, that's all I got. have a gud one! :p
