I think that a game where you can make your own custom Candy Crush Saga levels with elements from all four of the games, including massive boards and the ability to mix any types of levels you want, would be really cool. I've been making images of all kinds of crazy levels using a program called Game Maker and I would love for something similar to the level I have attached to this post to be playable. It's an idea that worked well for Nintendo and their Super Mario Maker games, so why not do the same for Candy Crush Saga?
