My big smile moment was in the level with a torturously long path between blue barriers that snaked around... UNLESS someone was on the blue barrier.
At that point, everyone was free to go straight to the exit (except the kind soul, who had to wait for someone to hit the cyan trigger and let them out)
I edited that out because I felt like everyone would just go top and hope someone would save them. By introducing a long path before they can help others, it makes them think "Well, I could just finish the level, or trust that someone will save me and help them..."
When I got to that level a cursor was drawing an arrow to a false path. I couldn't figure out how to draw, so I assume a "fake cursor" was part of the level.
