Re-Bunker

Oh, Noes! You and some of your friends where exploring and got trapped in Crazy old man Kirkpatrick’s Dilapidated bunker. The door slammed shut and locked you in. Good thing you guys know some science and stuff, you might be able to fix the door and get out, before you die from dehydration or run out of air. In Re-Bunker you must fix the door for you and your friends to escape but wait, there is more, every machine down there to help keep you alive is also failing. So you must keep them repaired till you can fix the door to escape, but if you send one of your friends to repair something, something else will start to break down.
