A shooter where you build the ammunition. Components go into the Potion-o-Matic, mixtures can be saved or discarded, and the result is what you fire — all on the left mouse button, including a click-hold-release gesture for the shot itself. That single-button discipline is deliberate: the game is about choosing a potion under pressure rather than about reaching for keys, and a badly stocked shelf is how the panic starts.
