At the moment there will not be any further layers to the frosting and adding adding a new frosting with even more levels will surely not make the game more fun and sweet. The Game Team is working on more different kind of blockers to the game to give it a new challenge on the levels.
Hi @Gamer5687 and @Spinnifix ! This is a good idea and the Game Team has already been working on this for some time. If everything goes as planned a Dark Chocolate Spawner will come into the game this year.
Hi @nish_23qwer and welcome to our Community! Not sure what you mean or how you would play this feature. Please feel free to open a new idea and explain the new game feature in more detail and how you could play it in the game.
