The coolest is a slightly more cinematic camera that can be put at any point in the level. This works pretty well for any beginning exposition or ending recap. This can be seen in the first couple screen shots.
Also of note, things don't have to be in space anymore and the sky can be colored and ground can be generated.
The other cool thing is the edition of scenery. I added some code to allow the drawing of anything you can model. They don't have much - if any - game logic or collision detection attached to them, but they can work pretty well for beefing up the environment. Usually they'll be to the side of the level adding ambiance or in a place that doesn't matter too much.
Finally a found a pretty large collection of creative commons music I like as well as a large collection of creative commons character portraits, so those are in there now. The portraits can be seen in the screens, the music cannot.
Anyway it's very game like now and you can even string levels together one after another. That's pretty cool in my books. There is no transition between them or anything, but it works. Right now the first 'level' loops forever.
The next big thing is to come up with a boss for the first level and a few more enemy types. Then I can start thinking about asteroids for the obligatory asteroid level.
I'm also ruminating on a potential plot. Honestly there doesn't need to be one, but it was suggested to me once that the characters literally always talk and I like that idea a fair bit.
