I got stuck for a minute there... I didn't know I had to drag the vents open. Up until that point everything involved pressing "E" to open... and my weapon being "fists" wasn't enough of a clue (clicking on the vents didn't do anything)
If a little hand indicator appeared over the vent when I clicked, or when I moused over it, then that might have been enough of a clue to figure it out immediately. I think that would have been more helpful than the narration being more descriptive, just a little bit of visual feedback to steer players towards the correct interaction.
The vents did feel nice to open after I figured it out.
