Having to play against the weapons you chose for yourself is a really good concept! The timing when you play as the boss is a bit short to kill the player, but it still works if you start shooting projectiles before the knight enters to kill you though...
Nice job ^^

I like the graphics and after I figured out that I can dodge the shock it became more fun ^^ However as a boss I always die instantly even if  battling only with a sword.

Nice idea, but is the "correct" solution really just spamming your keys? Works for me at least
