i'll give it a 9
great game, played through the whole thing and managed to grab 28 keys.
found the last two on my second try;)
a few things though.
whats with the "retry" function? why do you have it? why not just respawn at the checkpoint all the time? i don't get it
also i think i might have found a bug. or i did something wrong. but i couldn't play the extra challanges...
might be because i started a new game before i attempted the extra features.
i don't know.
amazing graphics though. loved the simple "black vs background"-style
and the choice of music was very enchanting to. it gave you that spooky feeling like "you're in hell and you need to get out". it kept you in there untill you made sure the crow was safe;)
again, great game and hope to see more.
peace.
