[SPOILER] Should there be achievements in AMFP?

[Thinker]

So I finally finished Amnesia again, and Justine, and I have a mac, so it is quite difficult to download Custom Stories, and I couldn't help thinking how much more content there could be if there were achievements.

It would grant access to a bunch of new activities, like killing monsters, or getting different endings (including the three secret ones) or reaching certain parts in the story.
I'm warning you now. I'm not sure how to bring up the "Spoiler Prevention" window, so I'm just going to write it out, completely un-prevented.

Examples:
"Houdini" For escaping the Cells without dying,
"My Greatest Triumph" For escaping Brennenburg, unphased by the Shadow,
"Demon Hunter" For killing a Brute (it's possible),
"Invisible Man" For engaging a hallucination in battle,
"Hospice" For making sure Hazel lives,
"Happy Hunger Games" For finishing Justine, killing everyone (I call it that because the recordings of Justine remind me of Effie Trinket)

It doesn't bug me as much as the subtitle glitch, but it would add another layer of things to do once you've finished.
