This is my game ClickerDefense:

How to Play: You basically play normal tower defense and protect your factory. But you don't get coins by killing the incoming enemys. Instead you have to click on your factory as often as you can. With the coins you get, you can build and upgrade towers and even upgrade your factory, to get more coins per click.

Fun fact: I just noticed that the play + rate round ends on my 16th birthday 😁
