I think this game would benefit a lot from having more combat options. Like maybe deflecting projectiles or a secondary sword attack. The sword swing is quite sluggish so gameplay feels quite slow.
Animations and sound effect need a bit of work though. I recommend adding sound for the sword swing as it's a core part of the gameplay.
Though if you polish it and add more enemy variety, this game definitely has potential. Keep making games!
Also this is pretty funny lol:
