Write the prompt around a playable rule
The prompt defines two attack shapes, matching cues and a response window. Keep attacks consistent in the opening so players can learn the difference. The vulnerable pause gives the player a reason to dodge correctly, not just survive. Use clear directional input and make the safe space apparent before the attack lands.
Original concept prompt: “Create a one-screen boss duel against a clockwork crab. It telegraphs a left claw sweep with a red arc, then a forward pinch with a narrow line. The player dodges left or right; after either attack, the crab pauses briefly and exposes its core. Show a small health bar and repeat the two attacks in a learnable order.” 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
Observe one full attack cycle without attacking, then try dodging each cue. Check that the arc and line predict the actual hit area, and that the pause is long enough to respond. If players take damage despite reaching a safe side, widen the dodge window or refine the hitbox. If the boss is easy to defeat without learning, reduce attack openings or add a brief cooldown.
Add a third attack only after the first two cues are reliable. Make it solve a different positioning problem and give it a distinct warning. Tune damage or pause duration based on several complete cycles rather than one lucky dodge. Ensure the health bar changes only when the exposed core is hit if that is the intended rule.
Do not hide attacks behind camera shake or overlapping effects. Keep the warning readable and the response consistent. A boss should challenge pattern recognition, not require guessing which animation is dangerous.
Playable reference for this prompt: Knife Hit. Tap to throw knives into a spinning target without hitting knives already stuck in it; clear the target to shatter it and face a boss every fifth stage. Use this example to compare the proposed rules with a game you can try now.
Questions about boss fight game prompt
What makes the two attacks distinct?
Give each a recognizable warning shape and a different dodge requirement. Keep the opening order predictable until players understand those cues.
When should the boss take damage?
Use the stated recovery interval after an attack. Test damage at the start and end of that interval so the exposed core matches the actual vulnerability.
