Flappy bulldog and Call Cristi.
Call Cristi is a side-scrolling mobile game. The objective was to direct a flying bulldog who moves continuously to the right, between sets of pipes. If the player touches the pipes, they lose. The bulldog briefly flaps upward each time that the player taps the screen; if the screen is not tapped, Bulldog falls because of gravity; each pair of pipes that he navigates between earns the player a single point.
