Carry four elements at a time. Tap one to put it in a slot or take it out.

Cast two elements at once (two keys together, or two buttons together on a phone).

On a phone: drag anywhere on the left half to move. Tap Strike to hit where the little arrow points (the way you last moved), or tap the right side of the world to strike toward that spot. A dashed ring shows which creature aim help has picked. Press two element buttons together to mix. Hold Focus to slow time. Turning the phone sideways gives you a wider view.
