Game not working, can someone help?

I'm trying to build a game based on a lovely template created by Jonathan Hill with Tinder's look and feel. In my case, the match is whether it is a vegetable or not. If it is, the learner swipes right, if it's not a vegetable, the learner swipes left. (For each correct answer you get 10 points).
So far, it works well.
I wanted to incorporate feedback in case the learner's answer is incorrect; then the learner has to click NEXT for the game to continue. It does not work for me. Can someone explain to me why? I added feedback only on the first slide at the moment (Apple). The feedback layer is "SWIPE RIGHT" in this case. I would appreciate any help.
