True 100% is the fourth and final category and displays all that this game has to offer. This includes the normal route as well as the hard route, with 10 eggs collected throughout the journey - nine from the normal route and one from the end of the hard route.
To get 100% in the most efficient way, play the game as a normal 9 eggs run until the 8th egg, "Under Ground." Once you crack this egg, select the chapter where you stand on top of the platform before the mosquito (this is the only time selecting a chapter during a run is allowed). Instead of jumping into the pond, head down the ladder and finish the game hard route style, without forgetting the final egg "Going Up."
