What can you get only once (and still have an interesting mechanic)?

You Only Get One Match (make your way in the dark and bring light to the world)
You Only Get One Key (Open the right keyhole to get other keys)
You Only Get One Torch (make it last – sequel to the One Match game
You Only Get One Bottle of Oxygen (go back to base to recharge it before getting asphyxiated )
You Only Get One Friend (can you recognize her/him?)
You Only Get One Path (will you take the right path?)

I could make a top-down rpg where you start with One Match and your goal is to bring light to your room/house/city/country/world/galaxy/universe (à la Katamari). But am I able to make such thing in less than 40 hours? I don’t think so…. Should I try? Maybe! Yes! Oh man….
