Nice rhythm game, the mechanics themselves are very simple, you can change the controls, and that helps a lot. I didn't encounter any bugs, the music is cool, and in general, you can finish the main campaign in just a few hours.
Now, if you want to get all the achievements or complete 200% of the game, good luck, it's ridiculously hard since you have to achieve tier S+ (challenger) in all stages in the three existing modes.
Overall, it's a cool game to grab during a very good sale
