Oh no! Well that shouldn't be happening. We were a little pushed for space so the dialogues can cover the rail dock in the kid mode but the dialogue should only cover the unlockable track pieces which aren't available when you're going through the tutorial. Sounds like a bug if it was covering more than that, sorry about that. If you have a chance to come back to it, please can you take a screenshot so we can investigate for a post-jam update?
