There is a "GUIDE" section on this actual page:
How to use cheat codes | Comment utiliser les codes de triches ?
In this section, you see how to use cheat codes.
BUT, next update will remove the "lights on" from "cheat codes" and add it to the control system instead. I am working and trying to find time to finish a proper control mode for the coaster, as it was never intended to be controlable.
