Hello. Thanks for reminding me to reset the continues after clearing a stage; that's an oversight. You should be able to continue at least once per stage before you get sent back to the start. I'm not even really sure if I'll keep this system; I'm trying decide on what kind of continue system would be the least frustrating without removing the challenge of the game. There is an option for toggling the player's hit-box, but it's kind of hidden. You have to press T on the keyboard. As to the 2nd boss's attack, I agree it is a bit too difficult. I think the main problem is the rows being random in addition to being too close together, especially if you're at Hildegarde's speed. I'll change it to be a bit less extreme. Thanks for playing!
