Thanks for your feedback!
Well, the shadows aren't my fault. That's the way stencil shadows work. However, I will take care with dynamic lights when I really build a level.
The spacebar behavior was my choice for the kind of control... while you hold SPACE you are grabbing on things.. but I may change this according to suggestions. What do you and people thing it would be the best way?
btw, it shouldn't float in front of the ledge. If you stop holding SPACE, the player should fall. But this is because the new OBB collision system that makes the collision spheroid 'stick' at ledges sometimes. I'll look for a solution for this.
