What feature to set, so that game does not exits on wrong selection

[shi2rs]

Basically, the use case is more for customizing when you add more nodes and levels.

The behavior of door 2 (yellow) helps you remain in the game to try out other options while the door 1 (red) makes you complete the game (and hence begin fresh).

How do I set the behavior for any node to remain in the game nor forcing me to reset the skill.

The instructions imply that the colors of the nodes don't impact the gameplay, but only serve to guide organization of the nodes.
