Why 2 things make hard mode easy in Going Medieval

I've gotten requests for help with dealing with hard mode or people mentioning they hate losing villagers, so I made on a video on the two things you need to beat back those brutal early game raids once you up the difficulty. I know I didn't focus on dealing with them enough my first couple of tries and lost a couple villages before I realized how much you need to invest in strengthening your defenses to stand a chance. #goingmedieval #goingmedievaltips #lowpoly
