A lot of people already made the same comment, but I'll just add it anyway:
I absolutely love the concept, but it's too difficult for me.
To me, it feels like the sword should not collide with the player, and I found it strange it didn't collide with the walls.
There's also no indication of when a mage will throw a potion. There's no buildup to it, making it difficult to gauge which angle you should protect first. I think there should either be a buildup animation/progress bar, or bigger levels, where you'll have more time to react to an incoming projectile. For instance, the first level with 5 mages has 2 mages very close to the player. Trying only to defend yourself without killing the mages (because you need one of them to kill a different one) or colliding with yourself is really difficult.

Having said that, I really like the sound effects and visuals. That simple wobble animation for the walking knight makes all the difference in the appeal. The slow flickering of the lights adds the feeling they're dynamic, and they also match the pace of the game (just like the music, by the way). The particles and screen shake on collision add so much to the feeling of polish. Great job!

All in all, I think it's a great concept, with a decent implementation.

PS. I saw your comments about updating it after the gamejam. I'll definitely keep an eye on it, because I want to see what this game will become. It has serious potential, and I wonder what it'll be without the gamejam's time constraint!
