Starting with good - art is really great, animations are cool (though sometimes buggy? idle animation looked like blocking), and also the music and sounds fit quite well. Different enemies looked interesting, especially the dark red knights.
About gameplay I'm mixed. It's really repetitive and one way'd - you hit enemy, jump behind it while they're stunned, repeat, repeat. Either that, or you get repeatedly stunlocked and die. Though it was cool to grasp how it works and kill multiple enemies without getting hit.
Also I suppose that "You win?" is the end? It doesn't seem to progress further
