I've just started playing the demo that came with the PCG disks. I must say you've done an amazing job. While playing the game I noticed some very interesting things about the creatures in the game.
Have you read the novel "From a Buick 8" by Stephen King? It's just that the flying creatures bear a striking resemblance to the one in the book, and there they also had an unbearable stench.
It's really awesome if you borrowed from that universe, or maybe even made your story in the same one. Or maybe it's all a big fat coincidence. Either way, it's cool.
