Hi, "wake up" is not in italics on my screen. At first I even saw the 'html' brackets like this [i]wake up![/i]. Then I checked Enabled to On in Bb Code in the RichTextLabel node. Then I ran the scene again: now the [i] brackets are gone (interpreted?) but still the wake up is not in italics.
It's a known issue, I just haven't had the time to make an extra lesson to cover how to set up fonts for the rich text label.
We'll get to this as this is logged in our tracker but we have a ton of work to meet the May 31 deadline to ship the last release of the course. We're just swamped and can't get much extra help at this stage.
If you want to make the changes yourself, you can add the fonts to either the RichTextLabel's Theme Overrides/Fonts or you can get some practice with the theme by adding them there. The different font types (bold, italic, etc.) are in the project.
After adding the fonts to the theme, my UI looked like this:
When running the project now, the italics are shown.
