One Button Wizard

You are an all-powerful wizard with mastery over hundreds of elements, but for some reason you only want to use two of them. Create powerful spells by combining the two elements using only a single button. Fight many deadly monsters, each with their own puzzling attack patterns, or fight a friend in a wizard duel!

Use Z (for player 1) or M (for player 2) to cast your spells using any combination of three long or short taps. If you hate discovery, then refer to the spell cheat sheet for a list of spells.
