The game does not require the participation of two players, you can manage the characters in turn. First, go through the level with one hero, and then after pressing the kept, you can switch to another hero and also collect spheres. Consider the situation changing at each level. Heroes should help each other. One collects the key, and the other opens the doors to them and so on in Repo and Repo.
