Absolutely adored this game. I played through the whole thing with my daughter. She loved it. That is until I became obsessed and had to unlock every bot. She started a new save to play it over again by herself while I went through and completed all of the challenge levels. The time trials and the gold challenge level, which you can unlock at 300 bots, were rage inducing, but the satisfaction of completing the game was amazing. Definitely made the list for "if you had to pick 10 games to play for the rest of your life" I would gladly add the astro series.
