Write the prompt around a playable rule
The prompt makes the tap response visible and gives two upgrades different roles. A stronger pick improves every action; a helper changes the rhythm of bonuses. Showing cost and effect supports deliberate purchase. Keep the first session short and avoid a prestige layer until these choices produce a noticeable difference.
Original concept prompt: “Create a tiny gem-mining clicker. Tap the crystal to earn one shard; every fifth tap triggers a visible sparkle bonus. Spend shards on either a stronger pick that doubles each tap or a helper that triggers a bonus every third tap. Show the next cost and the effect before purchase.” 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 a fixed number of times before buying anything, then buy each upgrade in separate runs and compare the result. Check whether the cost is deducted and the described effect matches. If upgrades feel identical, change one effect rather than adding more options. If tapping becomes tiring, make each input responsive and keep visual feedback concise.
Tune upgrade cost and effect separately. A first purchase should arrive soon enough to demonstrate progression, while later purchases can require more deliberate saving. If one option is clearly dominant, give the other a distinct payoff such as quicker bonus cycles rather than a smaller version of the same multiplier.
Do not bury the basic tap under menus or automatic effects. Let the player understand where shards come from and what each purchase changes. Avoid promising offline accumulation or export features that the prototype does not provide.
Playable reference for this prompt: Spark Forge. Hold to pump the bellows and heat the blade, release to strike inside the glowing sweet spot, and finish each order before its clock runs out; coins between runs buy bellows, anvil, apprentice and metal upgrades that transform the forge, then rebirth in the stars. Use this example to compare the proposed rules with a game you can try now. For your version, use this check: How do I make the two upgrades meaningfully different?
Questions about clicker game prompt
How do I make the two upgrades meaningfully different?
One changes the value of a tap while the other changes bonus frequency. Display those effects and compare several short runs before adding more upgrades.
Does this recipe include passive or offline income?
No. Its proposed rewards are tied to tapping and triggered bonuses. Passive production would be a separate mechanic with its own timing and persistence tests.
