Once upon a time there was an I and a t. "Bah" said the t, and left. "Where is t?" I was wondering. And started the quest. You will play as I on its quest for t. This plays like a puzzle/platformer. I can move left or right, and grow and shrink but not jump. The edges of the I can be used to grab onto objects and then pull itself up among other ways to utilize I shape to get through the levels.
