It's really fun, screen is too tiny so you need to at least 2x or 3x it imo. Both enemy and sword mask seem smaller than it should be where you're chasing 1 pixel to hit the ghost that's standing right in front of you so I'd get them larger, I think you should at least get the sword one wider. After you get hit it doesn't feel like you have proper time to recover so overall although enemies have nice behaviour about them even when they're predictable outcome changes because sometimes they can hit you over and over and sometimes you can get away with that tiny window of invincibility frames, I would also get the iframes last a bit longer, I don't mind 4 way movement and combat is fun enough to play for a good while, definitely going to steal some enemies.
