A downloadable game for Windows, macOS, and Linux

Terra Nil is a relaxing city builder about ecosystem reconstruction.

My take on the theme was that starting with nothing was just a barren wasteland that you need to rejuvenate.

The 6 buildings I managed to create form a nice circular dependency so expansion is always a little difficult.

Some protips 
-  Start with a turbine
- Order of building matters (e.g. you need to place the greenhouse after the scrubber)
- Pay attention to the overlays and tooltips

The procedural generation can technically create an unwinnable state, but I don't think this should happen and if it does, just restart

- Left click to select
- Right click to deselect
- Mouse wheel to zoom
- Arrows to pan
- R to rotate
- Esc to bring up the menu

- Unity
- PyxelEdit
- WolframTones
- Audacity
- Bfxr

Keep up the good work! It has high potentials! 

Tried playing on the smallest map. The map did not contain any rock tile, making it impossible to continue. Retried with a new map. Same.  Retried with a new map. Same. Retried with a new map. Same. ...

Tried large map. Finally got a rock tile to be able to start playing.

Advice: Ensure that the maps created are actually playable at all.

Good game! And my steam controller went really smooth with it too. I guess you should put animals and humans too. (Like i dunno.. Controlling humans against contamination or some invadin wood cutters i guess?)

You are clearly a very talented individual. It's a simple game but very aesthetically pleasing and well made. Especially considering you did it in 48 hours. definitely going to check out your other work now. 

Thank you!


Must say, this game has potential. I enjoy games about managing things, mining, and farming. This one has some small issues in its current state. It needs to be fleshed out more with additional features and information.

A game about the ecosystem has a lot of options to choose from in expanding it. Hope to see this go further.

Thank you for your kind words :)

Great demo! I like the core concept and the artwork. The experience is relaxed and is very much a puzzle of building things without running out of money. I suggest you add a passive income to balance against some sort of  enemy (encroaching toxins?, environmental raiders?). I think the water pumps should be able to flood a limited number of squares. You probably have a million ideas as well. In its current state its enjoyable but very short. Thank you!

Cool ideas, thanks for playing


Cool! But small/easy often generates maps without rocks

Yeah, thanks for letting me kno


why do we have to download it just let us play it without having to download the game


"Arrows to pan"
Any chance of a WSAD option? :)

Ah! It really does need some quality of life improvements

Looks really neat!

Thank you!

Awesome, thanks!


This sounds lovely, any plans to further develop it?


Thanks! Not sure at the moment, sort of depends on the reception, I've got a lot vying for my attention :)

Thought about something like this before I'd cheer you on if you took this further.



How play this on 2560x1080??

Did you try the windows with resolution dialog download?

I only use Linux

Try again. The situation has not changed


rocks never seem to spawn on the small map? this was quite enjoyable though, interested to see if you intend on expanding this. 

Yeah there's a bug there, thanks for the heads up!

Hello, tell me how to solve such an error: The application "Mac" can't be opened. OS Catalina

Sometimes OSX doesn't let you open files from the internet. Try CMD+Clicking on it to open, if that doesn't work let me know

did not help

Check this article, maybe you need to change your security settings https://support.apple.com/en-us/HT202491

I'll also do another build, just to be safe

The problem was in the built-in MacOS archiver

Aha! I'm glad you solved it :)


Alright, here's my feedback on the game:

  • Nice art and good background music. Though, the UI does go well with the art of the world.
  • The difficulty doesn't change over time. It doesn't matter how big your green area is, the game still has the same difficulty. This is because there is no passive income from your green area. This feels unfair.
  • The area of buildings is shown well. Though, it would be nice if you highlight the part of the world were they can be placed. I also think that you should better show if a building (powered) is within the range of a turbine.
  • If you place a building first and then place a wind turbine, the building doesn't receive power even if it is within range.
  • Please add the ability to see the range of a placed turbine by mousing over it.
  • Panning with wasd and panning by holding down the middle mouse button would be nice.
  • Maybe add the ability to remove buildings as well. Though, not having this does make the game more difficult. So perhaps allow destruction on low & medium difficulty and disable the ability at high difficulty.

Interesting ideas! Thanks for the feedback :)


Good fun, satisfying to play. Some feedback: the leaf symbol doesn't match the graphical style, buildings should be orange when over suitable land but out of range of electricity, add keyboard zoom controls (I'm playing on a laptop).

I like the orange idea, and I agree about the leaf symbol yeah 

Thanks for the response. Also forgot to mention that the little symbols that appear as you collect money move in a strange way if you pan at the same time, the speed should be unaffected by the relative speed/direction of the panning.

Is there any hope to get a windowed mode? I have a ultra-widescreen and the ui is off :/

Sure, are you on windows? I can make a new build

Yes I am

I've uploaded a separate windows build which should allow you to pick your resolution and play windowed :)

Thanks! Its annoying that this setting window is so hidden at the moment and will eventually removed in the near future. Its so convieniend in my opinion. 

A very nice little game. More!

Thank you!
