I love this title and its dlc! I have 100% the game, performing pacifist runs on all of the run n gun stages, and completing all of the bosses on hard mode. I found the doctor to not be as difficult as many have found, nor king dice, but I had an EXTREMELY difficult time with the dragon boss fight. Its art style is so aesthetically pleasing and it is so hard not to appreciate its hand drawn animation. Major hats off to this studio in Microsofts magnum Oppus of this generation. Also… spawned an amazing review by gaming journalists.
