This time, the birds and pigs are fighting it out in space, and the birds have rocket drives. There’s gravity in some places (near planets), and not in other places (not near planets). Only it’s not as simple as that. The existence of a gravitational field is shown by a red disc centred on the planet. Inside the disc there’s gravity, with the force directed towards the centre (I can’t tell if it’s 1/r^2 or constant on my little tiny phone screen); outside there’s no gravity. Gravity just switches on when an object enters the disc. Real gravity in space doesn’t work like that, of course.
Outside the disc, in the no-gravity regions, things travel in straight lines. So far, so good, maybe. But they gradually drift to a halt. No gravity, okay, but friction?? (Which is why the birds' rocket drives are on all the time.) Real gravity in space doesn’t work like that, of course.
Also, there are some “black holes”: nothing visible at the centre of the gravity field, but stuff does get broken up if it goes there. There are also, confusingly, sometimes large planets with no gravity field at all, that act as hard (but massless!) obstacles. (Cases with invisible gravitating black holes plus visible gravity-free planets are particularly … interesting.)
There are two new birds: a light blue "ice cube" bird which freezes stuff, making it easier to break later, and a purple ("Lazer") bird that boosts in the direction of your tap (instead of the yellow Lazer bird that boosts along its tangent when you tap).

So, I’m just back from the Science Fiction Eastercon, where I was telling a friend that I’d nearly finished Angry Birds Space. So that’s all three done! (Vanilla, Seasons, Space) There’s also Rio, he said.
AAARGH! WHY DID YOU TELL ME THAT!
I’m now on Rio level four, collecting golden bananas…
