I thought that looked great – though again I would start with a shorter tunnel 😉

I think a shorter tunnel will bleed off less speed and enthusiasm. Here, they have to travel such a long way once they make the right choice and it delays the reward. If you’re threadling to the far side, they can initially make the right choice but second guess themselves before they make it all the way to the entrance.

I guess I would just like to see you progress to the same kind of work but with more speed and enthusiasm (less thoughtful).

I think often thoughtfullness comes before drivey action. So it’s not a problem, I’m just letting you know what I’d like to see next. More action.

Along those lines, once they’ve “picked correctly” I would add some running on your part so they don’t just come back to you for the reward but instead y’all are running together out of the tunnel.
