The MacUpdate listing says this is a download of Fizzball 2.0.
In fact, it's a download of Big Fish Games' new downloader. When you run it, it downloads FizzBall version 1.02.
I already owned FizzBall 1.0, and this doesn't seem any different (no big surprise). Unfortunately, the downloader clobbered my purchased version of Fizzball with a time-limited demo. Whoops - I hope I have that backed up.
I'm a huge fan of the Fizzwizzle series, but Big Fish games isn't doing its customers any favors, as far as I can tell.
