Nice little game! Found a bug, though: the spider attacked me even after its death. There were some spiders camping outside my nest, but, after the speed upgrade, I was able to escape from them more easily.
Thanks for pointing that out. I thought I had fixed that bug but I guess not. There's also so supposed to be a function to push the spiders away from the nest but I don't think I pushed them far enough away. Thanks for trying it out.
