Thanks for the feedback everybody!
@Hypnos: By default right now, the game actually runs in a window that's set to the screen size. I'm finding that the only way to get good results is to edit Config.prc and not touch the window properties after startup. And I forgot about that port thing, I changed the default to 8081. Thanks.
And the menu/Globe.egg texture references are fixed too. All this stuff will be in the next SVN revision.
@ThomasEgi: I'd loan you an artist if I had any, but it's just me.
Anyway, I added a quick try ... except ImportError block for importing psyco, so it's optional now. Also, I'm running Windows 7 x64, and 32-bit psyco runs just fine. Don't know if 32-bit psyco runs on 64-bit Linux, but I suggest trying it if you haven't yet.
I'm aware of the wall-jump issue. You can actually make very small course adjustments while in-air by holding WASD, which makes it even easier to wall-jump. I'm fine with that, but I guess I should probably add ceilings to these levels.
Are you referring to the droids becoming partially invisible? That's supposed to happen, but if the cloaker droid is making the physics blocks transparent, that's a bug I've never encountered.
The mouse issue has long been my nemesis with this project. It varies a lot depending on the framerate. If you want to take a look at the code, it's in the "Mouse" class in src/engine.py.
