When you consume a red bonus block, the controls switch hands. The pattern of the controls ought to be obvious (direction keys on the home row). If the snake becomes part of a full row, by the rules of tetris the parts of the snake in the row will be destroyed. If this includes the snakes head, you will die. Apologies for the lack of animations to make this clear.
