I made a clicker game on unreal engine and it was pretty easy to make (I just used widgits and widgit switchers and buttons that took you to different pages). I didn't upload it on here but it was pretty well developed and fun. One suggestion though is make sure your clicker game works in browser because clicker games are usually more popular in browser where they can be played right away. Research which versions of unreal or unity allow to package for html ( I didn't and my unreal 4.26 couldn't upload to html and that's why I didn't publish my clicker game). Good luck and welcome to game developing!
