Write the prompt around a playable rule
The prompt defines automatic movement, an immediate flip and attachment behavior. A direction arrow can help players anticipate the switch, while wide early space teaches the movement. Keep spike silhouettes distinct from safe surfaces. If the robot can attach to either floor or ceiling, show the target surface before the flip resolves.
Original concept prompt: “Make a side-view corridor game where tapping flips gravity and a small robot runs automatically. Alternate floor and ceiling platforms with visible spikes. The robot attaches to the nearest safe surface after each flip; show a brief direction arrow before switching and begin with a wide practice corridor.” 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 in the center of a wide corridor, then near a ceiling and near a spike. Check whether the robot follows the arrow and attaches to the intended safe surface. If the switch feels delayed, separate the input cue from the attachment animation. If hazards appear too quickly, increase the preview distance before raising run speed.
Use obstacle spacing to tune difficulty. A wide safe section gives players time to reset their position; a narrow opening tests timing. Add one obstacle type at a time and verify that the safe route remains visible. If a flip is always the correct action, arrange a later sequence where waiting briefly is also useful.
Do not make gravity direction difficult to infer from animation alone. Keep the arrow or surface indicator visible, especially when effects fill the screen. A quick restart helps players experiment, but it should not conceal why a collision occurred.
Playable reference for this prompt: Helix. Drag sideways to spin a helix tower so the bouncing ball drops through gaps while dodging red segments. Use this example to compare the proposed rules with a game you can try now. For your version, use this check: What should remain predictable after a flip?
Questions about gravity flip game prompt
What should remain predictable after a flip?
The new gravity direction and movement toward the safe surface should be legible. Test repeated flips near a platform edge before adding narrow corridors.
How can the opening corridor teach the action?
Use broad surfaces and visible hazards so an early flip has room to resolve. Reduce that room only after players can connect a tap to the changed motion.
