Very confusing. I have no real idea what I was supposed to do or what even was going on at most times. I guess the slimes and rats were enemies. There was no indication at all that they were hurting me but the game suddenly just ended so I guess they did. I just kept wandering around randomly picking up stuff I did not know what it was or what it did and finally met my end by some slime I didn't know was hurting me.
The (keyboard) controls were awkward. Switching the commands (which I didn't really use at all because I had no idea what they did) with mouse wheel was not great at all. Probably would have been better with pad but didn't even try because you specifically mentioned xbox controller. And now I tried again and PS4 controller (on mac) worked just fine. Even the button mappings seemed the same. Did you use some Unity input add-on like InControl or that other one which I can't recall the name of?
The sprites looked good and the music was sweet (could have looped better).
