Can you get reappointed as fed chairman? (try this game to find out)

Is that the joke? I was able to manage to get it to 4.3% unemployment and was yet fired for having sub-2% inflation. Clearly whoever designed this is quite hostile to zero-rate targeting.

Problem with zero percent rate of inflation is that is rather too close to deflation for comfort. Generally speaking, the best strategy is to try and keep inflation at a low and steady rate (which is where the 2 percent target comes from) rather than veering to either extreme.
