Write the prompt around a playable rule
The prompt describes the launch direction and transfer condition. The preview should be a useful estimate, not a perfect answer if the game is meant to test timing. Keep planet spacing varied but reachable. A safe window gives the player something concrete to aim for, while the restart keeps experimentation quick after a miss.
Original concept prompt: “Create a one-tap space game where a spark circles a small planet. Tap to launch along the visible tangent toward the next planet; a catch transfers the spark into its orbit. Show a faint preview arc and a clear safe window around each planet. Missing all orbits ends the run with a quick restart.” This is a recipe for an idea, not a claim that this exact game is already playable.
Play, observe and refine one thing at a time
Tap at different points in the first orbit and watch how the tangent changes. Check whether the preview arc points toward the actual flight and whether catching an orbit is clearly signaled. If a miss feels random, widen the safe window or show the next planet’s orbit boundary. If every launch succeeds, vary spacing modestly after the first catch.
Change launch timing window, planet spacing or orbit speed separately. Start with wide windows and tighten them only after the player recognizes the launch cue. If you add a moving hazard, make its path visible and keep it away from the first transfer. Replay the same planet pair after each prompt revision to measure whether the cue helps.
Do not hide the launch rule behind decorative particles. Players should know whether to tap based on position, rhythm or target alignment. If the preview is misleading, correct it before adding more planets or score bonuses.
Playable reference for this prompt: Orbit. A spark circles a planet; tap to fling it off along its orbit's tangent and get caught by the next planet's orbit before drifting into space. Use this example to compare the proposed rules with a game you can try now. For your version, use this check: Which direction should the spark leave the planet?
Questions about orbit game prompt
Which direction should the spark leave the planet?
Along the tangent at its current position. Test launches from several points around the orbit rather than checking only the most convenient alignment.
How should a successful catch be shown?
The spark should visibly join the next orbit and become ready for another launch. Check that one catch produces one score event and does not immediately release the spark again.
