英文:
Clicking on an image not working as intended
问题
我创建了一个游戏，你需要点击屏幕左侧的图像，但必须选择不在对面出现的图像才能进入下一关。但出现一个问题，当你点击左侧的任何图像时，仍然会进入下一关。当你点击错误的图像时，应该显示游戏结束。目前只有在点击空白处时才会出现游戏结束的提示。有什么建议吗？

英文:
I made a game where you need to click the image on the left side of the screen that you do not see on the opposite side to get to the next level. For some reason, when you click any image on the left side you still go to the next level. When you click the wrong image it should say game over. Right now it only does that when the whitespace is clicked. Any tips?

将theLeftSide.lastChild.addEventListener('click', nextLevel);放在循环外部以使其正常工作。
英文:
notice
for (let i = 0; i < numberOfFaces; i++) {
let face = document.createElement("img");
...
theLeftSide.appendChild(face);
// you do this in every loop
theLeftSide.lastChild.addEventListener('click', nextLevel);
}
put the theLeftSide.lastChild.addEventListener('click', nextLevel); outside loop for it to work
