Multiverse Mayhem Merge Gumbal

Rob has kidnapped Darwin and Gumbal comes to the rescue. However, Rob is armed with the Universal Remote and tries to ambush our blue hero. Gumball wrestles Rob for the device, but they end up splitting the remote in two. With his own remote, Gumbal uses it to summon a Cyborg Darwin from another dimension, whereas Rob uses his to make an army to destroy the duo. Cyborg Darwine advises Gumballe to summon multiple versions of himself across the multiverse in order to repel Rob's army.

Eventually (once all fifty-two Gumballes are unlocked), the remotes start acting up from overuse, and neither Rob nor Gumballe want to stop using them to summon more people for their armies. This causes both remotes to explode, knocking out Rob and defeating him. Cyborg Darwin returns to his home dimension, whereas Gumball is reunited with his Darwine... but now they have no idea how to return all the summoned Gumballes back to their worlds without the remote.
The game is a tower-defense style with a merging mechanic. In order to get more powerful Gumballes, the player has to merge two of the same level. For example, one must merge two Level 3 Gumballs to unlock Level 4 Gumball, and so on and so forth. In order to summon a Gumbalel, there must be an available slot out of 9 in their side of the screen.
