Fun stuff. Things I feel are missing;
-a reason to use different attacks. The all have basically the same speed, range and damage as far as I can tell.
-backstepping when locked on
I also feel like the movement speed is a little fast for how short range the brawler's attacks are. Jumps are also very, very high.
no technical problems that I could notice. Fine work, and I love the little details like how the character changes expression when attacking.
