Wow, this is a really unique story, the use of expanding passages is something I've never really seen before, and the voice is really well done, I really enjoyed this piece. I way you describe being a cow is very detailed and does a good job putting the reader in the perspective of a cow. The ending where you click "You are a cow" several times is really satisfying. Nice work. The only thing that is a little glitchy is some of the text animations seem to happen when there is not text visible, so it looks like the page is changing height, that might just be a twine error, not sure what's causing that, but it might be empty content with animations attached.
