I hope I'm not doing a necro here...
but I really must thank-you for putting this tutorial up.
It's been literally the ONLY shadow tutorial I've seen that I can understand.

Anyway, bellow is my *basic* implementation result (In Pascal). It's not quite finished yet (don't have multi-light mixing working yet or shadows that aren't fully black I'm also planning to make shadows soft by drawing a gradient image along the edge of the shadow).

I wish I could get over to Pax XD
I've been lurking this topic for a while and I really must say that I absolutely cannot wait for this to come out! I love the style!

Also with the glitch boss, I love the code XD
