Thanks for playing not once, but twice! I think you're the first person to do that besides me, so that's awesome to see!
I feel the swords add some replayability! I personally like using the Rapier because of how fast you can shoot charge shots! If we had more time, we would of made the swords more like classes with different numbers of hearts and charges. I think that would of really spice things up!
As for the Boss, his health is definitely a bit too high and going forward I will make sure to avoid that!
