SFCave clone update

Standard

Last night I didn’t sleep since I was at a lan party, so I made a lot of mistakes this morning while working on my little game. I wrote some sprite code to show smoke, after creating a sprite doing some photo-editing in gimp. Then I made a separate display list for the tunnel obstacles so they can cast shadows on the tunnel.
I think it is looking really cool now, so I uploaded a video to YouTube, here it is:

I am still going to put the video on pyCave’s website.
