GREAT GAME!!!
I was never stuck in the game, so i guess i would be able to wake up from a coma. you have to pay attention to all the small things, i would post what to do and all the little secrets but this is a test for you guy, see if you can get out of the "COMA" :).
To the author: this was a very deep game, at least for me, keep up the good work man!
