City Stacker
Mobile arcade game where you build your city by stacking the houses yourself.
A house swings on the crane, tap to drop it onto your building. Every floor that lands raises your score, but if a
house misses the stack and hits the ground, or the building tips over the edge, the game is over.
Play the original version on itch.io.
Running the game
The game is made with Godot 4.7 using the Compatibility renderer, so it runs on
desktop, web and mobile.

Game is the root of the main scene. It handles input and the score and connects its children through signals, the
children never reach up the tree. Gameplay values like the rope length, swing angle, house physics and camera
behaviour live in the resources in resources/config/ and can be tweaked in the inspector. Positions are configured in
world units like in the original Unity version: one unit is the height of a floor and 10 units fill the screen height.
High score and mute setting are saved to user://save.cfg.
Development
GDScript is statically typed, untyped declarations and unsafe access are treated as errors in the project settings.
Formatting and linting use gdtoolkit and run in CI:
pip install -r requirements-dev.txt
gdformat --line-length 120 .
gdlint .
All assets are stored directly in git, Git LFS is not used. The whole assets/ folder is about 400 KB, the music is
an Ogg Vorbis file.
History
City Stacker was originally made with Unity in 2021. The Unity project, including the ML-Agents experiment that trained
an AI to play the game, is still available in the git history before the Godot port.
