It's kinda like a Cookie Clicker, but better. It's a bit more complex and, thus, more engaging to me. It is complex enough to provide a stimulating fix of dopamine, but not time-consuming or intellectually taxing. So, it's perfect if you need to fidget with smth during convos or to have a quick game break which doesn't require much time commitment from you.
