I think I got some kind of glitch??? On 3-X right as I failed I kinda spazzed out and clicked a bunch, and the game froze for a second. When it unfroze, I was still at the end of 3-X, but the song was playing from the beginning and I was no longer able to fail. So... free badge I guess.
I hate everything about this game. From the way there's no auditory feedback for when you hit notes, to the control scheme, to the laughably poor input recognition. This has been the most hard earned shiny kongpanion I've got and I hope there's never another week this miserable.
As a man who plays over 3 hours of rhythm games a day, i can say this: some of the songs are crap, but some are good. The ones with vocals especially, it took me a long time to notice that the beat is synced with the barely audible background sections. If you can't hear it, you're better without sound, which is something kind of unique to this game: a rhythm game being easier without hearing the beat.
