Wow. It's not even done.
I know this wasn't on the planned features list, but I have added the ability to put backdrop images into the game, like nebulae and such:

I also redid the graphics for all the ships, and put a green background around the images so that I can remove it to make them be transparent, allowing stuff like what is shown in the picture. The sun and warp hole are still the same, but with a brightness --> alpha filter.
Now I have to update the features/bugs list.
Edit: I have not yet uploaded the new version. It may take a while, because my computer isn't letting me edit this one folder while explorer.exe is running; I have to CTRL+ALT+DELETE and exit explorer.exe, open the dos prompt, manually delete the folder, run explorer, and recompile.
Edit: If you would like me to explain how to make maps, I will tell you. Just ask.
Edit: I have uploaded the new jar and miscellaneous files.
Edit: And if anybody can tell me why it is giving people the "cannot find main class" error when there is a clearly specified main class in a clearly existing manifest file, it would be greatly appreciated. Thank you.
Edit: I have come up with a solution. I have wrapped the jar file in an exe using JSmooth, and packaged that along with all the needed files in a zip folder, which I converted to a self extracting exe using NSIS' Zip2Exe program. Then I uploaded it to rapidshare. Since it is only one file and contains everything, you no longer have to worry about the bs three minutes rule.
http://rapidshare.de/files/35863904/Installer0v91.RAREdit: this link is missing several images. Get the images from images.rar and stuffv0.9.rar on esnips.
I am also aware of the bug with the Build Colonizer icon, I will fix it shortly, although now that I am doing things this way new releases may be further apart.
Edit: that's a lot of edits!
