Well done on this! This is a very unique art style so far with high saturations. Quite fitting with the electric theme you are going for. Using the platform to the game play makes the battle interesting.
Moves was also varied which caught me off guard for some for the rare moves as they hit like a truck lol
Few feedback I would say is
1) since this is a very high saturation color, creating contrast for player and important attack anticipations would be difficult but necessary.
2) Control response is a bit slow, maybe make it more instant for player and longer recovery for effect
3) Damage might need to be balanced a bit, as it is currently too punishing. or alternatively gives a better tell of which attacks that will be coming.
Overall I enjoyed the fight!
