You can fall onto and walk on the water under the bridge in the second level - I doubt that this is intentional? In addition, the pause function doesn't turn off the mouselook :/
Nice models! Seems to take a while to load, though - you might want to add a progress indicator. The lack of sound also takes a lot away from the experience :/
