Best tool for this job

Bolt.new

Prompt-to-fullstack app in seconds.

Bolt generates a playable web game from a prompt—HTML5 canvas, physics, input handling, the works. Perfect for validating mechanics before committing to Unity/Godot.

Also worth considering

Cursor

AI-first code editor that writes, edits, and debugs with you.

Cursor is better for iterating on a real engine project, but if you're just testing an idea, Bolt's faster.

Getting Started

✓ Do this

→Describe the core mechanic clearly (e.g. 'physics platformer with grappling hook')
→Ask for keyboard/touch controls from the start
→Iterate in small steps (add one feature at a time)
→Share the link to playtest immediately

✗ Avoid this

→Asking for a full game (scope small—one mechanic)
→Not playtesting early (iterate fast)
→Expecting production quality (it's a prototype)
