I can figure out how to get outa the first room in the demo, Someone help me.
***SPOILER***SPOILER***SPOILER***
Brook, I'm assuming you know the basics, like jumping and walking.
You've got to climb up onto the high ledge on the left side of the room.
To do this, pull the rock that looks different to the left of the ledge with the torch. Then climb up onto the block, then vault onto the high ledge.
Keep in mind that when you're walking, you won't fall off of a ledge.
