Radioactivity vs. Nonradioactivity

After all, a big focus of our game is that every action has a reaction. This is not only reflected in the character design, but also in the environment. 

Left and right shows one and the same level. However, it is shown once in the friendly, bright variant and once in the radioactive variant. 
How the environment behaves depends on the player‘s actions - if he decides to use the radioactive variant, the environment will behave as shown in the left screenshot, and vice versa. 
For both decisions there are advantages and disadvantages in the whole game. In this particular case, the player manages to get to the other side more easily by climbing a radioactive mushroom - on the other side, the way down is closed.
