Art, aesthetic, and theme are all amazing in this game. Some of the bosses are designed better than others. The bishop was a great fight. The queen was a bit of a let down. It does seem like the best strategy on all the fight however is just to keep slashing and just barely think about defending. I was able to pretty much just mash through most of the fight. Also there are some loading issues I think. Whenever a new attack was going to be used it would lag the game. Could be good to preload assets before the fight happens so it stays smooth throughout. Also small little bug, the knight can overlap if you don't move when or after he charges.
Good job :)
