I've gotten nearly all the recent humble bundles. They've been increasingly good.
It must be a wonderful feeling to work on software and bizdev for them, too. You know you're making money, helping developers and artists, and giving to charity. I hope the people in charge are doing well.
They've been great and I got most of them too, including this one, but it's not better than the first Android bundle with Osmos and the World of Goo. Osmos alone is spectacularly good, it's the best indie game I've ever played -- the idea, the mechanics, the music... it's incredible (no, I don't know the author but I bought it three times).
Wow looks great.. You might also enjoy Orbital for game boy advance.. Relaxing and frustrating but with kind of similar gameplay, albeit more focussed on gravity slingshotting.
