The sprites and animations are put together well. Other than the particle effects and the UI, the art style is cohesive. Quite a lot of thought has been put into the combat system of the game (details like the hit animation is awesome).
There can be some improvements though. It is quite challenging sometimes due to the player's reach, but once you corner the enemy it becomes too easy as you can just infinitely combo them, and the jump is a bit too floaty like you are on the Moon. Overall, the system seems to be quite complete and I see the potential in working this into a full game!
