wow, i'm so impressed by what you've done!
the art is fantastic and the story is engaging: it defenitely keeps the tension ^^
i couldn't figure out the room at first as the hint is very subtle, as you have already said (dead end helped but i would never got it without knowing where to look) it also feels that there is a bit too much punishment for using the mechanics that actually let you play through the game. i wish i could begin from the point where i stopped and not start from the very beginning :)
and the hand was so scary when it first appeared, i jumped a little haha
one of the most unique entries, i had lots of fun playing and would love to know how the story goes on :D
