Then it's likely that beat-em-up isn't the genre for you, because this is a very solid entry in the genre. If you've ever played a bad beat-em-up you'd be able to see the strengths more clearly. A huge thing is that this game feels like it has weight in the attacks, and that's really hard to do. That's a subtle mixture of responsiveness, sound effects, animation (not just movement but also text/visual fx/flashes/etc), and more. And the hit boxes seem to be pretty much perfect, which is another aspect many games miss on. Then there's lots of nice subtle touches - invincibility frames, juggling, bosses with phases, and much more.

Nothing revolutionary, but a bunch of different parts all working together well that are generally implemented at a very good to excellent level. That's way better than most can say. Of course the walking animation, like the one guy mentioned is hilariously bad, but fixing that's also just a prompt away. Oddly enough I didn't even notice it when playing.
