Great idea for the game! I love your 3D graphics in the game. But it is not clear why you need to team up with other zombies. These zombies only get in the way. When you bump into something, they do not die one by one, but all at the same time. You also have broken colliders in the trees. My zombie flew past him, but got caught. It is also very annoying that the main zombie is not in the center of the screen. When a union occurs or one of the zombies dies, the camera jumps. This is extremely inconvenient!
It is very sad that at the end the road simply breaks and you fall endlessly! And there is no way to get out in the game.
