Bad luck! I've played this game a bit myself (admittedly not much good at it haha) but I made it to about day 90 on I think a 55% modifier. What I found most useful was rushing out to clear some choke points between trees and cliffs to make some easily defensible postions. I've heard that the AI will probe for your weakest defense so you can try and anticipate where they might come before it happens. Either way nice video - look forward to seeing if you can beat it!
