I could not have come up with a clearer warning, but seriously, did you have to take that jab at people!? I'll have you know that the abyss of the heart is not for the faint of heart nor is staring at it for too long recommended for those without an iron will or experienced at the hobby...
Okay, maybe not that extreme. Yet, for me who is a 'veteran' of the field, it is relatively tame. (Note that there are different areas of that abyss you need to become a veteran, with just a few transferable skills.) It is mostly a case of not wanting people to run headfirst into something horrifying that traumatizes them to the core of their being; that they'll never forget; than discouraging the general populace of ever interacting with the abyss. it's my first time watching, so I estimated it to be about something me from 4 years ago could handle.
You've either proven that estimation wrong, or sent inexperienced people to an abyss that will change them forever... Let's hope it's the former.
