Hey, thanks for the feedback! I chose to have the sword deactivate in order to force the player to change their pace a bit during battles - from running around kiting the enemies to luring them away so you can safely activate the sword again. If you plan it right you can use the activation phase to your advantage too!
Oh and I definitely wanted to flesh out the enemy types but wasn't able to get to that in time. Nice idea on the sword disabling enemy, maybe I will add that :)
