I felt that the game lack any real objective. In your GDD you say that little alchemy inspired you, in little alchemy, you combine for example water and fire, it produce steam, it make sense.
In your game you combine red and yellow potion to make snail (I think) and I feel the game combine elements just for the sake of combining them.
However, your artstyle is excellent and the music is cute. It's pretty chill all around
