Nice start to what could certainly be fleshed out with additional enemy types, monster features, and inventory management. In lieu of an actual inventory, I quickly learned to use the floor itself as my inventory, saving potions for when I was no longer certain to beat an enemy and retreating as necessary. (Or, in some cases, deferring to take a potion, expecting the level up healing to fix me up in time. : )
I think there's a small visual bug on the final boss, as his health bar didn't decrement as he took damage. However, I figured that may have been done on purpose to obscure his strength.
In any case, he was no match for my fierce fighter. 💪🏼💪🏼
