You did a great job here making a boss who feels fair but fun to dance with. It encourages slow play over just spamming attacks, because if you dodge right behind the fox to take a swing during their attack, you get pulled in, possibly right into the damage zone. So you’re encouraged to hold back, to attack only between attacks.
Then the final phase comes and flips this on its head! That one took me several tries to get through, but really i think the hard part was getting to it with more than 1HP.
My biggest critique is really more a Skill Issue™ on my part: it’s possible to have the dash animation with no movement (by holding shift but no arrow) and if fingers are confused in the midst of battle, that animation adds to the confusion: the leggies are movin’ but i’m very much not!
Congrats on making a fun, hard fight.
P.S. at the time of this writing the game page says to move with A/W but i think you mean A/D
