I recently picked up Crypt of the Necrodancer on a steam sale and I have to say... why the heck didn't I play this sooner? I'm not a huge rythm game guy but CotN changes the formula enough to keep me invested. I'm not a fan of like, Guitar Hero or Friday Night Funkin but a rhythm game with combat and more complex mechanics is right up my alley.
The art is cute and the music is awesome but the gameplay itself is what truly shines. You move on each beat, meaning higher BPM songs are far more difficult. Each enemy also does their behavior each beat which each behaving differently and usually telegraphing their next move.
