So. I guess the game does not get attention very often (which is a shame, it was awesome) and it may explain why I did not found it mentionned here, but there seems to be an area right of the main hub (with the doors leading to the parts of the game), you can pass the wall by dropping the light not so far from the wall and jumping on it. By walking carefully on the piece of wall remaing, to the right, you'll notice the camera moving like when you reveal an area in a level. Thing is, it's entirely black, and there's no way to get a light through here because the wall is from ground to ceiling. And there's not really a ceiling, not that you could reach it and go from above anyway.

Qestion is, what is here or was supposed to be here ? Nothing or a small secret for curious people ? Since I can not see a thing... It bugs me ^^ (happened a lot in the game: levels are incredible bu you never get to see the art fully :p )
