The pixel art is very good, though some moves are somewhat hard to see where i do or do not have control and i'm missing a bit off feedback when hitting them, the player looks megastrong, but the impacts of his attacks are minor. A bit of hitstop and screenshake would make this feel a lot better i think! As a game, looked really solid, could be very awesome with a bit more love and caring ;). Well done!
edit: if the jump were binded to say spacebar the control schema would've have been great, this was just a bit clunky at times.
