Resetting the map, bosses, and losing drops is fine, I like it.

That's good!Regardless of whether that's souls-like or not.
game should not be too easy，good job！

Losing drops is just bad. Resetting boss is good. Resetting random trash on death is kind of questionable but also doesn't really matter that much and is only bad because the current map generation makes maps that are twice as large as they should be.
