I think a lot of people here would probably agree it wouldn't be a bad idea. Mechanic should be solid for a little more than just a small game though :)
I just added a new mechanic to the game. Instead of parrying, you need to attack to "parry" attack. I really want to complete the game this summer, gd luck to me. Also, I wonder if you would interested in trying out this boss. I could send you a private link through discord or something.
