There are like double hits on the notes of the songs which makes my brain think to tap two times. But in this game its really hard to do that because I also need to see and understand my screen, it would have been better if there was no double hits of drums because I cant get the rhythm of the base beat, which is annoying if this is a Rhythm game
Sorry, I just tried to make the rhythm the same for every song. When you shoot, it actually shoots 2 times.
My advice would be to train on the first level to get the rhythm so it starts to be automatic. Also play with a controller and a headphone, it's easier.
Or, you can cheat the game and go past all levels lol.
