Black holes and more levels

Keep your astronauts from slipping into the black holes!

Since the end of the game jam is very near, I've dumped the rest of the levels in, although there's not much new in the later levels. While technically you can play forever (the levels just start over), there are now 17 different levels.

I still have one more level type I'd like to get in, but it's unlikely to be done by the end of the jam.

How many astronauts have you saved?
