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!

Fun game, overall I liked it. But would be nice to get an generator for the workers and be able to click thru buildings. For me the unnamed key building didn't seem to work. 

When you constructed the key, nothing happened?

Sorry for the bug, I'll try to see if I can reproduce it.

Oh, and I'm working on a building to generate population. Thanks for your feedback!

it's a nice game, i really lke it but i would like to save.

Also put a limit for the game area or a button to go back in the center of the map, i put my cursor on the top of the screen and a few secondes later i totaly lost my village

Hey! Thanks for your feedback, you can press space in order to focus the camera on your village. The info is hidden in the help menu.


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
