reading the whole and its parts concurrently
Type the digits of π while pressed the a, s, d, and f keys when the digit matches the numbers on the screen.

LEVEL SWITCHING here refers to the ability to read multiple levels of data at the same time. When reciting π, it feels natural to me to want to take in additional information. In this game I ask my mind to switch not only from one task to the next (that is, sequentially), but between different ways of reading the same shapes.
