Hi, I have a question about the rules.
In our game we have multiple levels and in each level the button does different function.
For example in first level we use the button to move the car. Then in the second level we use this button to shoot from the car (the car moves otherwise). Basically the button has one function per level. Is it allowed or is it against the rules?
Thank you for your answer.

Yes, it is allowed.

You probably want to tell the player what the button does every level, otherwise you might confuse them.
