The single player mode will be released with 24 levels which may seem like a walk in the park but after the first 3 levels things will get pretty hard. Levels will not have the same goal. Sometimes you will have to sink a ship with bowling balls other times you will have to eat candy. or avoid a crazy electric beam separating you from your destiny.
You will get a whole new background after completing 8 levels, the background more background in developement. this is still in concept phase.
