God the Gullivers made me jump the first time they came along, I wasn't expecting it at all! I thought it was a cosy town building idle game, I was just relaxing, then those giant idiots showed up!
Yes, best to zoom in and rotate the map to begin with on each level and see which direction they are going to come from. You get about 30 seconds before they attack so enough time to throw a tower up if you have the resources!
