You've made a lot of improvement to the combat.
The regular enemies had tougher AI, and the Boss seemed fairer.
I had a lot off trouble with the encounter just after gaining air dash though.
It seemed like the only viable way to beat them was to parry, but if they weren't in sync, one or both of them would whoop me. Not sure if there was something I was missing.
I accidentally skipped the instructions at the beginning. I wanted to see the next slide, but I guess it was on an auto timer.
I took to using over hand to use the dash ability since it needs quite a fast input. Maybe consider putting dash on one of the bumpers. Maybe. It's fine as is, but it might be more comfortable to let the player keep their thumb on the Jump button when they want to perform a dash>jump>dash.
All in all, great job on the concept so far.
I'll post my recording when it's up. Having some audio issues with it.
EDIT: It desyncs quite badly towards the end. I think the rest is OK.
