I spent a lot of time working on this level, so download it and have fun!
Read the readme. 
Download it here: DarknessGishLvl.zip
Wehey I love it!!!!
I dont think the darkness really added much to it, but nice idea on making gish a light source.
I love the way the heavy blocks carry you down to the lava and the little floaty block you ride down the lava on.
The weird ending was also quite cool.

P.S. How do you make light sources, I know its object 8, but they always come out as anchor points for me.
Thanks. 
Anchor points *are* lights. To get them to work, click on the anchor point and set Ltype to 1 for constant lights or 3 for flickering lights. Then choose the RGB values and intensity and press F5 to refresh the level.
clever ending, heh
Ugh, I tried that before and it didn't work. Thanks!
Great level, there are a lot of nice ideas in there. It runs like hell on my computer, though...
It's only a 900 MHz Athlon, so I have no right to complain though.
Nice level. Only a bit easy.
Also is this still available from somewhere? The link no longer works
