In the level "Highway", a billboard of Arin Hanson, popular YouTube animator and co-host of the web series Game Grumps, with the tag line "Face In The Game!!" can be seen passing by. Anyone who had pledged to the game's Kickstarter $2,500 US or more could have a 2D representation of their face somewhere in the game. Arin also appears in the game's credits as 'Mighty No. 12226'.
