The game is interesting. But I suggest giving the player more feedback that the weapon is actually being used.
The sfx only play when you're near the enemy.
The jump is too small and feels insignificant, and the sword is too small and can only be used when too close to the enemy.
I'd say maybe get a bigger sword and maybe add a small swing animation to give more feedback also always play the swinging SFX.
Nice work tho.
