The game mechanics are pretty impressive, with a little more refinement it can be a great game!
In addition to the minimap, I think it would be good to work more on the scenario, putting some elements that can serve as a reference point for the player, or an easier alternative would be to make the floor have different colors in different areas, as if they were "biomes", this way it would be easier to find your way around, and it would be clearer in which direction the player should go.
