A very nice interpretation of the theme, really liked the idea.
The mechanics are simple but clever, and the game is fun to play and controls well. It was a little bit on the harder side for me, as I don't usually play games like this, but I really enjoyed the gameplay.
Really loved the dual purpose of the potions as I could use them either on me or on the player.
Also the small touch of music getting louder when You're closer to player viewport and quiter when you get away is a neat addition.
