Really interesting, when running with flash debugger client got these errors:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Platform3D/checkEndBrickCollision()
at Platform3D/collisionAndGravity()
at Platform3D/movePlayerAndCam()
at Platform3D/enterFrame()
After I hit the red block and finished tutorial.
Anyway, looks really interesting, I'll be sure to follow along.
