I have mastered this game and I can say wholeheartedly that this is one of the greatest games of all time. This game has one of my favorite styles, it is based off 1930's cartoons with silly animations. It has a well-crafted 2D style and is an amazing boss-rush game. This game has 5 main sections, Isle 1, Isle 2, Isle 3, Devils Casino, Delicious last course. They all have perfectly crafted bosses with a very good difficulty, having most players dying at least three hundred times a run. The DLC Is one of the most amazing things in this game. It was in development for five years, only having a few bosses but it was worth the wait. This game has an incredible charm system and health system. It is a masterpiece. Recommended.
