My Overlord! The stars will soon be aligned, we have to rebuild R'Lyeh and forge the Unnameable key to the Ultimate Gate and awake the one true god: Cthulhu!
May his reign endure beyond eternity! FHTAGN!


  • Idle/clicker mechanics
  • Build  your base
  • 10 upgradable Buildings types
  • 5 Resources to manage
  • Three levels of difficulty
  • Many tentacles

Click Of Cthulhu was born from the idea of creating a city building game on Gameboy. The game was created in one week with Unity. Not a single line of code has been written to make this game thanks to Playmaker!

Black Flag

Black Flag is cooperative of two friends based in Bordeaux, France. We brew independent games and develop hopped beers! Our next game is called Orphan Age, it's a dystopian simulation game where you look after orphans left behind in a cyberpunk war. You can play the demo here and here.

You can support us by adding orphan Age to your wishlist on Steam or by joining the private Alpha today at:

Really nice game

Thanks! <3


Hi, nice clicker, even if i would prefer not to click one by one, but either hold mouse button down. It would physically hurt less. Also, i very often missplace a road when i want to place a building, not sure why. Playing on Linux with installed version. I'd love to see a more advanced game if you keep working on it.

Maybe you could introduce a "trainer mode", in which one click would grant the player some 25~50 rocks, so as to avoid the exhaustive clicking, but focus more on the strategic aspect.

Nice concept of a humour, good presentation, very clunky user interface, classic theme of a gameplay. Altogether, a solid city-sim, I think. If you like clickers, that is.

Thanks for the feedback. Can I ask you what issues did you have with the UI please?


In some layouts, placing a construction on a square behind yet another building, can be tricky. Universal mark for assigning of a construction is samewise as the one indicating the library in particular. These are the ones I remember best. There are other minor things, but I guess whether one thinks of them as an issue or not, depends on getting used to it.

Thanks a lot, I'll try to get this fixed next update.


Really nice game, it makes you want to turn into a speedrunner (without even liking chthlhulhtu...), well done :)

Thanks <3
