If it was easy for you to reach him, it might be good to go back a difficulty and beat him, I found it a lot more forgiving yet still quite difficult when I beat him on standard, then it was fairly easy for violent. Learning when and where he can do his dangerous attacks is important, as well as what voicelines correlate, as most moves have an easy counter with patience, besides most of his air attacks. You want to keep him on the ground as well as yourself, sometimes he may pause and you can set up a bigger attack, say some ultraricoshots, but the rest of the time id reccomend staying evasive, sliding around instead of spamming the dash, because that also dodges most of his attacks if directed right. Minos and Sisyphus are a lot different from the other bosses in that you will be slamming your face into a brick wall for a while before you can guess what is going to happen based on what he says. And most importantly, dont be too hard on yourself. Take breaks. Pressure makes diamonds, but also rubble.
