Layer Tutorial Series | Part 12: From Prompt to Playable Ad

What does it take to go from a single prompt to a finished, shippable playable ad? In this tutorial, Alex Engel, VP of Product at Layer, builds one from scratch using the Layer agent: a portrait-mode lane shooter called “Mochi Rush.” Alex starts with nothing but a prompt and a few reference assets, then lets the agent do the heavy lifting: researching what’s working in lane shooter mini-games, defining the art direction, generating audio, and coding a fully functional playable. Then he polishes it with a few rounds of plain-language feedback. In this video, you’ll see how to: - Use the Layer agent to research current trends in lane shooter playables - Upload character designs and art references to steer the visual style - Generate an Art Bible: your theme, palette, and keyframes in one place - Create a custom sound pack with background music and sound effects - Use the Playable Code Generator to turn your Art Bible, assets, and game logic into a working prototype - Let the agent run balance checks so your game is winnable but still challenging - Iterate with natural-language requests: parallax backgrounds, higher-quality 3D enemies, richer UI, tougher hordes, and a harder boss fight The result: a stylized, low-poly 3D playable ad that comes in under 2.5 MB, built with roughly 2,000 creative units (about $120) including every asset and iteration. If you’re a mobile game studio or marketer looking to produce playable ads faster and test more creative, this is what that workflow looks like end to end.
