Going boss by boss, the Owl is the worst one because there are parts of the screen where he cannot ever hit you, and the most reliable way to hit him is to stand there and spam arrows, which is just long and tedious. There is no way to tell where the Worm is coming from, and it broke often due to the worm jumping off the screen. The Mole was the most fun and fair fight, and took us a while. I feel that the weapons should do more damage, especially the arrows
