Wonderful game. My only disappointment was that there was not more levels to play.
Now for feedback. I feel like as a player you are a bit too much at the RNG's mercy. If you're using full randomness, maybe try a random bag to make sure the player will always get acess to an item they need at some point. Aside from RNG, the mechanics are solid. The boss fight is cool in a way, but being stuck against the wizard's face due to their insane movement range makes it that you either have to just wait and tear through them with your items and heal every time you can, or be unlucky and get stepped on completely. Maybe reducing its movement to 1 and giving it an additional mechanic to spice up the boss fight could help with it (like giving it the ability to attack from a 2 range or to sometimes run away from the player for example).
Either way, it was a very pleasant game to play. I also really liked the story and chara designs
