I like the idea of the game. At the beginning I couldn't see the caracter so I thought the game was in first person and didn't get it, maybe adding a window or starting with the player in the corridor would help.
I lost some time trying to jump to the first ramp and failing (at the left side). I would move it to the left so it is touching the wall and the player cannot get between the ramp and the wall. Took some tries to jump at the right time, but when I finally did it the "movie sequence" was nice.
This last comment is not about the game itself but the "packaging". I understand it´s a gamejam and it takes some time, but at least adding more screenshots would help the possible players get what the game is about. If possible, making a nice looking image showing a clapperboard/camera would probably help in that aspect.
