Splash/Intro screen for Game - Eco Beasts Warrior

Found a live stream where the team looks at animating walking sprites using the hero sprite and the normal animation blocks - frame animations.

I have been able to replicate this and works fine…I think!

I have tried to use the print dialogue block to have the text story appear on the screen story style but have simply tried to change it for the show long text block - problem is that it appears but the screen changes and startLevel is called before the end of the dialogue.
I don’t know the solution, but is it possible to use an if statement and to say while the showIntroduction function is playing not to startLevel?

Thanks!
