Debug Mode Setup?

[Xanthos]

Thanks for reading,
I know there's a debug mode thingy.
I'm not sure what it is or what it does.
I believe it's and easier way to test the script/map without having to go through the whole map and everything.

I've already made a story and a half and For me to test everything I have a lantern placed at the start of all maps and I go through startup/login and I have to test the entire map everytime I add more scripts. And If it crashes I have to exit it off and keep the message with the error there and have to listen to the annoying sounds That sometimes play when it crashes.

So pretty much is what I'm asking is
1.) What is debug mode?


2.) How do I set it up?

Once again thanks for reading
