I might submit something shortly *cracks knuckles*
If you guys have at least 1024x768 resolution, you can just press alt+enter to go full screen and then do a printscreen or something. I use HyperSnapDX for my screen capturing but you could just press the print screen key and then paste it into a paint program.
There is no other way currently to screenshot the whole level and include the lights and stuff unless you take several screens of the level and piece them together.
Oh, and the level with the blue roof and all the custom graphics.. those graphics look like they were taken from this other old online game I saw recently. The biggest giveaway was the leaf shadow overlay, because it's pretty close to the other game I saw.
My favorite has to be Shadowless Warrior's so far.
