This game is fun, but only when it works, which is rarely. Constantly the game will freeze for about a second and lose you multiple notes which could cost you the whole song and ridiculous amount of energy that is needed for it, the song will lag and jump back by 5 notes, unsyncing the music with the notes and completely ruining the rest of it, notifications from the game, such as 'can't connect to the internet' (while it is connected to the internet just fine) will not pause the game, rather make you lose every note that plays while it's on screen and then pop up a few seconds later, the game is always redownloading all its songs every two days, which makes you wait until it's downloaded EVERY song for you to play one song that you'll probably lose from one of the buttons freezing, which just happened to me, and also after every single download, it says 'Oh no! Something went wrong!' not telling me what went wrong or why, but seems ridiculous for something to go wrong after EVERY SINGLE SONG, and it will probably make you redownload it again within the day anyways. Every minor bug fix update gets worse, like the past 4 updates, the icons for goals during songs were not aligned correctly and no one noticed for 2 more updates, and currently, the sound effects like boosting and getting an achievement is delayed by a few milliseconds, enough to irritate you. The energy is ridiculous, your limit rarely goes up, so when you get down to the last story you can only play twice every few hours. I've finished the last story section called Source (where you find out they very lazily named all of their story sections after the name of the song in the lobby, which gets very irritating very quickly), and it still says I've only done 50% of each room, and won't tell me how to finish them, most likely cause I'll have to pay for something. In the arena, you can be better than the person you're playing against, play on a harder difficulty, do better, but still lose only because they payed for their Beat Monsters during one of the poorly designed events that happen every other day. The story of the main story is terrible. I don't pay attention to it and click through, but when I do read it, it says something stupid like play this song to scare them out, play this song to start the boat, play this song while I catch my breath, they all are the same thing that just do different things, the same song could turn on the security system, and also kill the most powerful person alive. The songs don't get harder as you progress, so it gets stagnant fairly quickly. If I wanted a better story mode, I would probably have to pay for it, right? I'm more worried about the game breaking parts of the game than the story, so if that was fixed, I would be happy as well as many others that I know.
Just checked on the new update, free UNLIMITED* play, with unlimited only being for a month so people can get far in the paid stories, then not be able to finish without paying to your garbage app
