Muse Spark 1.3 builds a Subway Surfers clone, but needs explicit prompts

A tester found Muse Spark 1.3 produced only a basic endless runner on a simple prompt, improved when asked to research mechanics first, but still missed features Gemini 3.8 Flash added in one shot.

ok, i ran the same test on Meta Muse Spark 1.3 Attempt #1: “build a Subway Surfers clone” it gave me a basic endless runner 💀 deleted it. Attempt #2: “research all the mechanics of Subway Surfers first, then build the clone.” Way better. but it still missed stuff Gemini 3.8 Flash added from just: “build a Subway Surfers clone” custom skins, double-tap hoverboard, more mechanics, etc Muse Spark can build but you need to be MUCH more explicit with it. Gemini seems to understand the assignment better i put the Muse version below try it yourself and tell me what you think ↓ link in the comments
