Barely

Your hand wraps around the handle, and you wrench on it. The handle resists for a second, then gives, the door opening with a slight squeal. You start to hurl yourself through the door, but are abruptly stopped as a tentacle wraps itself around your right foot.

With a startled yelp, you fall forwards, slamming into the concrete. You jolt as your bare nipples strike the cold surface, causing you lose your grip on the knife, and it clatters away, just out of reach in the corridor beyond. The tentacle begins dragging you back into the chamber.

As you slide across the floor, you manage to flip yourself over, your nearly-bare ass dragging across the slime-covered concrete of the chamber. A quick glance shows the tentacle is wrapped around the middle of your foot, as another one winds around your left, and a sudden burst of inspiration grabs you. Summoning every bit of strength you have, you manage to sit up, and your fingers claw for the laces of your boots.

With a slight cry of triumph, you undo the knots in your laces, and loosen them. You then kick your feet, your boots starting to slide off. The tentacles try to tighten their grip, but all they succeed at doing is yanking your boots off. They shoot back towards the core of the thing at the center of the chamber, clearly surprised at losing their cargo, and you take advantage of the diversion, scrambling to your bare feet, and sprinting towards the hatch again. The slimy floor is even slicker without your boots, and you stumble twice, both times narrowly avoiding falling, before rocketing through the hatch, grabbing the handle as you pass.

The hatch slams shut behind you, a few metallic thuds ringing as several tentacles abruptly stop against it. Glancing down, you spot your knife, and snatch it up, before moving a way from the door a bit.

The corridor you're in is narrow, and poorly lit. About half the lights are dead, and several of the remaining ones flicker, casting portions of the corridor into darkness, and others to flash hellishly.

Pausing by one of the properly working lights, you take a moment to take stock of yourself. The list is sobering. Your shirt can't even be called rags anymore, as it's nothing more than a collar and several dangling scraps of fabric. Your pants are barely justifiable as a loincloth, one which barely covers your nether regions, and doesn't fully cover your ass. The concrete is freezing beneath your bare soles. You're liberally covered in gelatinous slime, some of it dripping from your hair, more from your nipples. You lost your pack somewhere in the fight with the creature, and all you have for weaponry is your knife.

Looking around, you can see a ladder next to you, leading to a hatch in the ceiling. There's another door a bit further down the way, beneath one of the flickering lamps, and what appears to be a side passage, hidden in the gloom between pockets of light.
