Pretty fun, although I think that the game needs some spice to sustain itself for the longer levels. While I appreciate not making the enemies pure bullet sponges, it does end up becoming button mashy due to how frantic the combat gets. And for that, I feel that controller support would've been a good touch there, as it's a bit uncomfortable on keyboard after a while. The game feels in some ways mechanically better and worse than the games its inspired off of. It feels more free form, and one of your best calls in this game is the near dodge. Where in other games a time stop effect works about as what you'd expect, here it's just an added layer of spice that's there to tell you "this guy is so good, he stopped time" and it's so over the top I love it.
I really liked the air of over the top humor on top of it too. All in all, I thought it was fun. Although I think the levels could've used more tropes in specific, to make it feel more varied. I like my beat-em-ups, but pacing is important too. And to do that you'll need to switch it up from just "fight more" at times. It's fun, but it gets repetitive.
PS: Newgrounds version took forever to load, while Itch.io version loaded really fast for me.
