I think it saying "You're eyes are opening" is not a mistake as it then says "th een'd" (or something like that)
Anyway... good game... and... I'm not certain what happens at the end... Maybe his sister is the fly thing, and she's actually dead, so she is encouraging him to give up being in the coma and join her in the afterlife?
OR, a better thought just occured. It's a comment on euthanasia. His sister visits him in the coma and gets the doctors to believe that there is no chance and to turn the life support machine off. The sister is not in the basement because she's... deserted him, or something, and the guide is somebody persuading them to turn the support machines off. The... thing in the clouds is another person the coma patient knows who is persuading the doctors to keep the machines on, but they turn it off in the end.
Also, Beginner is NOT HARD. I wouldn't call it ridiculously easy, but it is no harder than a 'Normal' mode in most games. I beat it first time with only 12 deaths, and found the locations of all 4 relics, though I couldn't be bothered to get the third one.
Intermediate mode, though... oh my GOD...
Erm, why can't I play on Intermediate mode straight away? That's not fair, I beat the first game on Hard mode...
Oh well... it'll probably get 5/5 anyway, the last one did.
