Since you’re using zones, you should make the title “How to make a game overlay appear and disappear using zones.”
I think you left out the wire setting for the overlay.
This is just a minor nitpick but you should make the writing more consistent. Some of the letters at the beginning of the step are capitalized while others are not. Also, step four isn’t aligned with the others and there isn’t a space after the “4.” This is just my OCD leaking out so you don’t have to change it if you don’t want to.
By the way, the ideas tab is used for questions about game ideas.
It’s main purpose is to be able to do things like I just said. Just wire the zone to the wire repeater, and wire the wire repeater to the game overlay.
