Kaiju Run is a casual game where you have to run around each of the scenes and try and destroy everything in front of you. At the start of each level, you will control a monkey that you can evolve by gathering the green pieces scattered on the ground.
In Kaiju Run, there are many walls, trees and other obstacles that you can only destroy if you have the necessary strength. This means that you have to go about collecting all the energy bars, so the monkey transforms into a King Kong-like beast.
As you make your way through Kaiju Run, you will also find some red elements that you need to avoid. These rocks will deplete your energy and make it harder for you to transform into a monster. What's more, when you reach the end of the race, you'll have to face random enemies like Godzilla or another huge gorilla.
Kaiju Run will test your ability to run through each scene while collecting the green pieces and avoiding the red. Just advance through each part of the route while breaking any obstacle that gets in your way. This is the only way you can get a good score that will let you unlock new skins and elements.
