Here's a critic if you want it, I hope its not too long.
This is a great fun little game so far. The gameplay is simple and easy to learn, and the art is well made. But I do have a few nitpicks. I'm sure others have brought it up, but the controls are kind of wonky. Id recommend something like this:
MOVE/CROUCH/JUMP: W,A,S,D or arrow keys
ATTACK: mouse 1
PAUSE: esc or enter
I also have a few nitpicks on the bosses and gameplay, nothing that ruins the experience just little things. The first boss could use a little more variety in attacks instead of just the 2, or at least making one of them more interesting. I was thinking, maybe instead of just a stomp attack, he could jump to the other end of the room and his landing causes the shockwave. I have no complaints about the 3 summoned bosses. And for the last boss, the only issue I had was with the knives. I like the idea of having a pestering attack that makes it harder to deal with the other attack, but the knives are too hard to dodge to be a pestering attack, as well sometimes id be mid jump and a knife would form in front of me or on top of me with no warning, giving me no chance to dodge. maybe there should be some sort of effect showing where a knife is going to spawn, or when the knives spawn in, they should have a fixed direction instead of locking onto you, but spawn in more often, as well as doing less damage. And my final complaint is on the sword's curse, once again I like the idea, but the bosses usually only gave long enough openings for 1 or 2 attacks, kind of rendering that mechanic pointless, maybe the curse bar could fill up quicker or it could reset slower.
