Subserve

It's a dystopian world out there, and you've been chosen as an expendable worker to investigate a meteor in the ocean. You must go down to the meteor over the course of 3 hours, but beware, you don't know what kinds of creatures will be down there. Luckily, you have been equipped with a "Fracking Device".

If you see anything at your window, use the Fracking Device as soon as possible to shoo it away. Using the Fracking Device costs power, so crank the generator clockwise to regain power; If you crank it while it's at 100% power, it will start overloading. If overload reaches 5%, it will dump all power from the generator instantly, down to zero.

basically FNAF but in a submarine

Credits are listed in-game.

If I'm being honest this game barely fits the theme lol, it only barely fits the theme because a submarine is small, hence "Limited Space".
