Learn Spanish (Spain): ¿Llevas superado el primer nivel? - Have you passed the first level so far?

While both can translate to "have you passed", using llevar + past participle emphasizes the accumulated result of an ongoing process up to now. This is why the English translation includes "so far". The present perfect (has superado) is just a simple statement of a past action.

In this sentence, does superado change if the object changes?

Yes. In the llevar + past participle structure, the past participle acts like an adjective. It must agree in gender and number with the direct object. Here, superado is masculine and singular to match el primer nivel. If you asked about the first two levels, it would be: ¿Llevas superados los dos primeros niveles?

Why does the English translation say "passed"? Doesn't superar mean "to overcome"?

The verb superar literally translates to "to overcome" or "to surpass". However, in the context of video games, courses, or challenges, it is the most natural Spanish verb to use for "to pass" or "to beat".

Why is it primer nivel and not primero nivel?

The word primero (first) drops its final -o whenever it is placed directly before a masculine singular noun. Since nivel (level) is masculine and singular, it becomes primer nivel.
