The pixel art and the animations are really pretty. That's pretty impressive!
In terms of gameplay, It felt really punishing. You really have to calculate your blocks and moves unlike other button-masher fighters, so it felt a bit frustrating. It has an intentional "sluggish" feel to it (well, I think it was intentional!) and I think it gives it its charm.
I'm not a big fighting game enthusiast, so I might not be the best to give feedbacks for this type of game! I enjoyed the experience however :) Great job on the submission!
