Description

A comparative experiment testing the zero-shot game development capabilities of Kimi K3, Gemini 3.6 Flash, Claude Fable 5, and Grok 4.5. The models were tasked with creating a self-sufficient HTML5 canvas game with unique physics and themes, producing playable results like "Graviton Core" (Gemini 3.6 Flash) and "Lucid Descent" (Kimi K3) while highlighting the failure of Fable 5.

Prompts

Prompt 1

Create ONE self-sufficient HTML file with a mini-game on canvas 1280 × 720 (without external libraries). Requirements:

- The player controls an object that falls under gravity and must to reach one's goal without touching obstacles
- DO NOT use "click-through jump" control - find another way interactions with physics (for example: changing the direction of gravity, time deceleration, wall repulsion, teleportation, inertia at pressed button - choose and come up with something yourself)
- Design the visual style and theme yourself - don't copy existing games
- Required: clear goal, score or levels, victory and defeat conditions
- 150-250 lines of code

Don't ask questions, don't describe the plan - just output the finished file one at a time answer.
