Use the cauldron to create metallic, ionic or covalent substances as instructed by the wizard. Use the keys 'n' or 'm' to add metals or nonmetal elements to the mixture.
The aim here will be for object sprites to appear on the top half of the screen in a 'random' fashion and for the player character to pick up the objects and drop them into the cauldron. I plan on adding either lives or a timer (probably a combination of both) with ramped difficulty and a leaderboard at a later date.
