Pepper & Carrot

I just came across an utterly charming comic called Pepper and Carrot that really captures the sort of mood I'd like to have in my hypothetical Potions Game.

This comic really contains a lot of what I'd want the potions game to be about: making potions and having adventures to get the ingredients. It is non-violent (though containing plenty of peril) and whimsical. It also suggests more things to make the game interesting, specifically competitions! Brewing competitions, broomstick races, etc.
