I hadn't tried the game since I was on my phone when I wrote this comment, but now having played the game, it was exceedingly boring to the point I don't get why you're trying to convince people that they're lying about how fun the game is. It's just not interesting!

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.

I find it funny you talk about how great the animation is, before immediately conceding that the walking animation of the main character (perhaps the most important animation) is "hilariously bad".

Look, this is obviously from a technical perspective, totally mind-blowing! Like I never in a million years would have guessed this could be possible 5 years ago. That being said...it's still not very fun or interesting. I think you are mistaking that mind-blowing feeling with the actual end product being fun.
