Text Based RPG

A really basic RPG I made in Godot in like an hour to test my programming skills.

Info:
Q to attack
E to heal
Space to use special attack

Special attack requires 5 mana, and you earn 1 mana for every successful hit.
You also use 1 potion for every time you heal, and you only have 10 potions.
Your goal is to defeat the enemy in the least amount of moves (moves are not limited in any way, but are a method of keeping a high score).
