Doomsday Clicker is, as its name suggests, a clicker where your goal is to create a thriving civilisation of survivors inside a nuclear shelter ... only to finally put an end to mankind and rebuild the shelter from scratch with all the experience obtained.
The game system in Doomsday Clicker is the usual within the genre: you have to wait for time to pass to earn money, and with that money you can get more upgrades that in turn will make you earn even more money. The goal? Having a massive shelter that can get you lots of money.
One of the best things about Doomsday Clicker is its sense of humor. The game has lots of funny bits, like the ways you can put an end to mankind or the kinds of structures you can build inside the shelter. You can also buy fun upgrades for each of the rooms you've created.
Doomsday Clicker is an entertaining clicker with nice graphics and a wide array of rooms and situations. The only drawback, of course, is how unoriginal it is.
