Well, this is pretty solid base for something more. Unfortunately, felt no juicyness or satisfaction upon destroying enemies - some knockback, some particles could have made situation times better.
Also, a sword attack feels much drier than jump&stomp - therefore, it seems to me, it is worth developing the second mechanic, as it could born many interesting ideas.
Lore is sweet)
Anyways, this is a good start. Thank you for this submission!
