Are the planet names from a predetermined array of names or are they randomly generated?
They are randomly generated.
Are you using the same random name generator code from your map random name generator that you used in several of your maps?
Good guess. Yes, it's pretty much the same thing.
is this map infinite, random off-screen generation, or a predefined wrap around map?
It's a continuous off-screen generation, but if planets become extremely far from the center, I delete them just to keep the game running smoothly.
Well you were right about the music. It was a perfect fit.
Are you planning to add anything else in the future?
Yes, I really want to add more stuff to this game, but I'm not sure exactly what. One of my ideas was adding an inventory system; you can find items on planets to trade with other planets. If you guys have any ideas, I'd appreciate to hear them!
Thanks all for the nice feedback.
