Very ambitious project! Cool to see the starts of a frame-based attack system. As far as the fighting mechanics, it's a very interesting control scheme that seems like it would port beautifully to mobile. One thing that threw me off was that you could move closer/further to the sidewalk.
Somebody like me who is spamming a bunch of attacks may accidentally move their character in doing so.
One thing I have to commend is the animation and collision systems. The attacks all feel fairly responsive, and the timings seem to work out as expected. I recall one time having both my attack and the AI attack land at the same time and we got simultaneously stunned. The transition between running and attacking, or between attacking and getting hit are all very smooth and very impressive to watch!
