Starting with movement, root motion to your main character would really help the overall feel as the sliding was very noticeable. I really liked all of the animations and the icons but there should be a lockout of all animations once an animation is used because currently you can just use every ability at the same time which looks weird and I am sure is not indented. I am unsure how the collisions work in this game but some sound effect being played when damage is taken from an enemy or the player would help a lot with player feedback. Another thing with the animations is adding root motion to them would force the player to stand still while they kick or punch which adds to the realism of it.
