A very promising start, the gameplay is already fun despite being so stripped down in terms of content. With that out of the way, here are my findings.
Pits are very unwieldy in this game. The player's fast movement combined with their character being instantly teleported back to the playing field makes the experience jarring, sometimes I didn't immediately notice I had fallen into a pit during combat. You should add a falling animation that takes something like half a second, that way the player can understand what's happening and get a brief moment to think of a gameplan going forward.
You can get jumped before being able to reasonably react when you enter a combat room, specifically when there is an enemy right next to the entrance. I suggest adding some sort of "wake-up" period for the enemies where they can move towards you but not attack. You could also add brief wake-up animations but I find it unlikely for you to do so given the speed of the game.
The game isn't too hard but it could use some balancing, specifically the slime enemies. I, too, was softlocked in the room with endlessly spawning slimes. Despite constantly attacking and using my willpower move on clumped slimes, I could not thin the horde down enough.
I have some other minor nitpicks, most of which were mentioned by other playtesters: there should be a way to restart/quit to menu when you die; attacks dissipate into walls sometimes; there should be prompts for interactables.
Everything else I have to say is positive: the music is awesome, the art is charming, being able to parry melee attacks is cool, and the gameplay is quite replayable. That being said, your environments are super bland. Consider adding some visual flair. All in all, I'm eager for updates. Keep up the good work.
