A bit too much going on on the screen, visually. The core idea is good - but with the design i don't see the difference between a block and a parry.
As you can spam parry, and have no drawback from doing so (atleast from what I've experienced) the game could be broken down to simple block = parry. How I played the first round (didn't notice clicking is a thing).
Visually I would remove the center animation, it is very confusing during the hectic movements around you and be more color distinguishing for bullets and background.
Well done for your first jam :)
