This is a great adventure, well written with good flavour. I like the mechanics for freezing and hypothermia which serve the coldness theme very well. Tavern, just being a trap for feeding the swamp witch, is a great idea. Ale-chemy is just hilarious!
I found it very difficult to read. The font is like cramped together and could have benefitted from more space between letters and columns. And it doesn't have much contrast to the background, a border around the letters could've helped here. My impression is, that you tried to squeeze the information of 2-3 pages into one single page. I'd like to encourage you to try using bullet points instead of whole sentences, to let the text breathe a little.
The content is great it's just the presentation that doesn't serve it well.
