I'm sure we're all familliar with the Endless levels. Pop Cap originally created Vasebreaker Endless, I, Zombie Endless and Survival Pool Endless. For those of you who like to hack the game, there exists Endless for Day, Night, Fog and Roof. What other levels can you think of you would like to see Endless for? They can be based off of pre-existing levels (both normal and Limbo pages) or your own ideas. Please fully explain your Endless level if it's not based off of somthing that Pop Cap created.
