The game doesn't work.

Aug 20 21:28:22 - [ERROR] - Exception thrown from SDL_Surface* ResourcesManager::createSurfaceFromFile(const string&) at src/engine/ResourcesManager.cxx:102 - File /home/luarocks/downloads/cytopia-linux-ci/resources/images/buildings/commercial/com_3x3_BureauDepoStefeCamp_RF.png doesn't exist

There is only `com_3x3_bureaudepostefecamp_RF.png`.


Great game indeed!

was the android port really made, using sdl and c++ ? 

yes, but the build that's currently being uploaded to itch is unfortunately broken.

  1. Un error en mi dispositivo móvil al instalarlo y abrirlo se queda frisado y te saca no puedo jugar

We're sorry about the error! The Android version of the game isn't currently functional.

Sorry, but how can I make it full screen?


press ESCAPE, go to settings and there should be a menu to go fullscreen :)

Thank you so much!!

 My video about Cytopia, building a nice tropical island city

This game seems to crash frequently upon placing water, electrical utilities, or zoning blocks.

This appears to occur with any object. It occured after almost every game.


I figured it out. Placing roads, demolishing them and them placing something over caused the crash. It's fixed now

Thank you! I've fixed the 1920x1080 crash and the update should be live now. But i cannot get the game to crash by placing objects. can you please provide a more detailled description, so i can reproduce and fix this?

Menu tiles do go out of the screen on debug->commercial.

We're working hard on a complete new UI that will resolve this and many other issues. Stay tuned :)

Works now. No crashes except for when pressing load game with no loadable game.

This will be fixed together with new UI. We'll add a savegame dialog that let you name your save files and choose from different ones.

Placing ground decoration, under debug->decoration->ground decoration has been fixed again.

roads on slopes do not work.

Roads on slopes should work without problems. The european roads (the grey ones on the right) had no slope sprites since they were not ready, but this was fixed by the artist too.

Fixed in last update.

Two of the european roads (I recommend numbering them to prevent confusion) have noticible gaps in corners now

Their image is not centered

Do you want me to move this to Github?

Game is awesome :)
