Brick Platformer
Author: OpenAI
Browser platformer game with brick rooftops and side-scrolling action.
Description
This platformer game was generated with Codex + GPT-5.5, using GPT Image 1.5 for visual assets. It places the player in a side-scrolling brick city scene with jump timing, platforms, and arcade movement.
Build notes
Initial prompt
@game-studio build a 2D platformer, full screen, using imagegen to create sprites and other assets, and use @playwright-interactive to test that it works well visually. It needs to be a simple 2D platformer built with Phaser where the character jumps on platforms and goes up a brick building.
Iterations
-
Generated the first Phaser platformer with GPT Image 1.5 sprites, environment assets, and in-browser visual testing.
-
Regenerated the character as a hooded climber with proper run and jump frames instead of mirrored placeholder motion.
-
Reworked the background so brick buildings frame an open night sky and full moon.
-
Iterated on platform spacing several times so jumps were challenging but the climb remained possible.
-
Fixed animation alignment issues that made the character shift vertically while running.
-
Added focused browser smoke coverage to verify the visuals and confirm the top-route treasure could be reached.
- Final step
Finished the platformer after browser checks confirmed the visual presentation worked and the final treasure route was reachable.
