Ollie Nom Nom is a side-scrolling mobile game featuring 2D style graphics.
The objective is to direct a large man, which moves continuously to the right, between each oncoming set of candycane walls.
If the player touches the wall, the game ends.
Ollie Nom Nom briefly swings his arms upward and jumps as high as the player holds down his finger on the screen; if the screen is not touched, peanutbutter jelly time. The player is scored based on the number of wall sets that he has passed threw succesfully in each run.
There is little variation or evolution in gameplay throughout the game as the walls only move up and down and are always spaced evenly.
However, Ollie Nom Nom has some subtle elements of gameplay design making the game easy to learn but hard to master.
