Since Jupiter is the largest planet in our solar system, it has the strongest and most intense gravity, which could be harmful to someone without the right protection. I suggest that upon implementing Jupiter, that you add an exosuit, or a version of the thermal padding with gravity protection. I think the exosuit is a better idea (mainly because its more fun), as something like that would give you increased strength and perhaps reflexes, although something like that has to come with a downside. I think it would have to have some form of energy storage and/or generation, say, a new kind of battery designed to hold large amounts of energy for the exosuit, and that you would have the same risk as running out of oxygen, in this case you risk running out of power and being crushed by the Jupiter's intense gravity.
