Which version were you playing — web or desktop? If desktop — thank you for downloading it.
That means a lot. If web — that's an old build. I'm updating it next week.
Just to be clear — I'm not asking to blame you for not downloading the desktop version. I just want to know which build you saw, so I know what I'm fixing.
About the city boundary: You're right — the city isn't truly endless. It generates buildings within a certain radius around the player.
I limited it because if I generated too many buildings, the resource pool would overflow and the game would crash. The "infinite green world" after the city stops is just the ground plane. It's not a feature — it's a limitation.
I'm working on a better chunk system that keeps generating as you walk. It won't be truly infinite, but it will feel much larger than the current version. Thanks for walking that far. That's more than most people do.
