This is the first mod that I see making its own tips&tricks thing. Really cool!

However I think the second and third tip don't really alternate the settings. For me what they demonstrate is the same every time. Or maybe the demo isn't affected by the settings? The code for switching the settings seems correct to me.

Or maybe the demo isn't affected by the settings?

This is correct. The demo ignores what the player has in their settings, to show off what is possible.

For me what they demonstrate is the same every time.

This is not intended. Unfortunately, it works as intended for me. Could you share a list of what mods you have installed? Or better yet, a save file, which will have the mod list baked in.
