Yup! Played through the first 2 planets, bought it, then finished the remaining ones. Took me about 4 sittings of 2-3 hours each. Amazingly fun, and just the right level of challenge. Every time I thought it was going to be too much, I took some time off, and came back and managed to beat the game.
Looking forward to more episodes...and yes I'll take a look at doing my own, too!
