Cursor builds and repairs a DeskHog Flappy game

Joe Black’s DeskHog walkthrough records building a Flappy Bird-style game with Cursor Agent mode and encountering a specific integration bug: the new game was not initially visible on the device.

The setup used a cloned DeskHog repository, GitHub Desktop and PlatformIO. Before requesting the game, the author gave Cursor the README and hardware details so it had context about the project. The request specified simple geometric graphics and the device’s center button as the jump control.

Cursor generated the code, while the human accepted changes and used PlatformIO to compile and deploy them to the connected hardware. When the game did not appear, the author pointed the agent at CardController.h and CardController.cpp and explained the problem. Supplying that interface context resolved the reported visibility issue.

The source’s broader troubleshooting instructions are advice for readers, rather than evidence that every possible failure occurred in this run. A later warning says the Cursor/PlatformIO installation process changed and recommends a different route. The case therefore preserves the original build-and-repair account without presenting the old setup instructions as current installation guidance. Human hardware testing and deployment were essential to detecting the missing game.
