Game Play loop
As I change the type of game, I'm working out how the gameplay will be continuous/forever. I have think have the basic play look figure out. It goes like this: play levels to earn points -> with enough points can choose and upgrade -> fight to actually get the upgrade.
I had wanted to work something in there with the nebula, as was part of the original game (reaching it was the goal), but I'm not sure how to do that yet with forever gameplay.
I may have the first playable levels of this new format online early tomorrow and you'll be able to play with the source code then.
Stay tuned.
