i love escape games and would highly recommend them to the fine people of ebaumsworld, as we all seem to have nothing to do all day but watch flash animation.
(kinda a classic)
(kinda the sequel of a classic... and equally creepy)
(think that one is on here)
and last but not least
Escape the room
(that one preety much speaks for itself)
if you get stuck, gamewalkthrough.blogspot.com is a good tool to escape.
