Mario-style platformer · llama-3.1-8b-instruct
Using the pre-provided phaser.min.js (global Phaser), build a playable side-scrolling platformer in the classic Mario style: run and jump across scrolling platforms, stomp enemies, collect coins, and reach a goal flag. Use ONLY procedurally generated graphics, no external image or audio assets.
This one-shot run produced no runnable artifact.
