Rhythm Heaven Fever is considered a hard game because, although it is only a rhythm game, it is pretty unforgiving about mistakes that you make, and can be very hard if you do not know how to play on the beat. It takes a lot of practice and a lot of effort before you will be able to complete the game without any faults. There are three different levels of difficulty in each objective, with level one being considered the easiest and level three being considered the hardest. If players reach level three, then they will have to start all over again. The first time a player reaches stage one and completes it, they will receive an easy start. The second time they'll receive an extra-hard star. The third time, they will receive the hardest star in the game, which is called the u0022Ultimate Staru0022. This means that if you can accomplish this yourself, then you are truly a master of Rhythm Heaven Fever and can do anything!
