Guiding through a maze and limiting the paths/space

Hi There,

I’d like to build a simple game, where the goal is to go through a simple maze with a circle. My issue is that when the sensor/mouse generates a signal far from the start point, it kills the original concept, as i would like to limit the player to go from start to finish in a predefined line. Assume that the below-linked picture is the maze, how could I limit circle path?

I already tried bullet solver and also applied elekktronaut’s collision technic. The first one is just not working while the other one seems overly complicated and doable only with straight well-defined zones which could be turned on/off. This app/community proved so many times, that I overthink my issues, therefore I came here :slight_smile:

Thank you for your help!
