Seems impossible? Just read the comments :
I personally think that when the steamroller goes over his feet, it pushes them into a cut out part of the ground and when it shows you his feet behind the steamroller part he moved his feet back up to create the illusion that he got ran over by the steamroller, and his AHHHHHH SHIT was played, Personally what i think!
Ok i think that when he gets run over by the steamroller he gets like in to a gap in the floor and the glass is real but he looks fir the small pieces of glass that dont hurt him a lot and why is there a white curtain on the sides of the steamroller in the front and he shoudl try it without the curtains!
i love how you can see the place where his body is supposed to go at 4:30 or so and all the little shards of glass are in the middle so it doesn't hurt him!
see how he is standing in a hole at 7:31 thefeet the camera shows behind the roler. fake!
.........
Still feel the same?
