I always thought games like these were a waste of time. But then I started playing one during my lunch breaks and now I kinda get the appeal. It's mindless, sure, but that's also what makes it relaxing.
One of my friends sent me a link that dives into this topic — whether idle games are doing more harm than good. I gave it a read and it really put things into perspective: https://www.uniindia.com/online-clicker-games-benefit-or-harm-examining-the-impact-of-idle-gaming/press-releases/news/3447527.html (https://www.uniindia.com/online-clicker-games-benefit-or-harm-examining-the-impact-of-idle-gaming/press-releases/news/3447527.html).
In the end, I think it depends on the person. For me, it's just a harmless break from the real world. As long as it doesn't affect your responsibilities, I say click away.
