Respect the return moment
Let players collect and understand offline progress before showing an item. Opening the game to an immediate modal can hide what happened during the absence and turn a routine check-in into pressure.
State time effects exactly
For a boost, show its duration, activation time, multiplier, and whether it continues while the game is closed. Permanent capacity changes should display the old and new limit side by side.
Test several return windows
Reload immediately, return after a short gap, and simulate a longer absence. The item, remaining duration, accumulated resources, and Koin balance should reconcile without duplicate grants or lost progress.
Observe several return windows instead of one click
This idle game uses an idle browser prototype centered on return cadence, visible progress, and low-pressure decisions. Review the genre through respect the return moment and state time effects exactly. For a solo creator, the content unlock should support that loop without becoming mandatory. Review the item through describe the included content and open a visible entry point. A solo creator should revise one prompt instruction at a time and compare both playable versions. The example offer is: A content unlock preview with a concrete description and direct Koin price. This offer emphasizes a durable, understandable extension to the core experience before expanding the catalog. Collect a known amount of offline progress before any offer appears and record generators, capacities, timers, and saved resources. Decline the item, close briefly, and confirm that ordinary accumulation continues. Try insufficient Koin without resetting the return summary. Complete a valid boost or capacity choice and state its activation time, duration, multiplier, and offline behavior. Reopen immediately, after a short simulated gap, and after a longer interval; calculate what should remain each time. Verify one deduction, one ownership or quantity state, and no duplicated offline reward. The free cadence should still feel deliberate rather than slowed to make the purchased relief seem necessary.
Keep the build finishable
Treat the purchase flow as one small feature inside the game, not a separate storefront project. Finish one offer, one confirmation, one delivery path, and the recovery states before considering another item or catalog category.
Reuse one item definition
Write the benefit, Koin amount, duration, ownership rule, and delivery location once. Copy that definition into the offer, confirmation, inventory, and test notes so solo edits do not create contradictory promises.
Use a short personal test loop
Generate the game, complete the core activity, decline the offer, trigger insufficient Koin, buy successfully, and reopen the game. Record the first confusing moment instead of changing several screens at once.
Ask one person to play cold
Give the link to someone who has not seen the prompt. Ask them to find the price, explain the item, cancel, complete the choice, and locate what was delivered without hints from you.
Use a one-evening revision plan
Choose the single player action that is still confusing and save the current build before editing. Rewrite only the relevant prompt sentence, generate again, and replay the same success and recovery routes in both versions. Keep a short note containing what changed, which version behaved more clearly, and what remains outside your implementation ability. Prefer a finished item with honest boundaries over a broad shop containing unfinished states. When asking someone else to test, give them the link and one goal but no walkthrough; their first hesitation is more useful than another hour spent polishing copy you already understand.
Trace the promised content boundary
Name the exact level, chapter, quest, character, route, or mode, describe its approximate scope, and identify the visible entry point that will open after confirmation. Complete the advertised core path without it and verify that essential clues, main-story resolution, required accessibility options, and ordinary progression remain intact. Buy the unlock, start it from the map or menu, leave midway, and find it again after reopening. Confirm that ownership replaces the locked treatment and does not require another Koin deduction. Review age context, rights, moderation, localization, save compatibility, and whether the public description overstates length or replay value. Bonus content may extend a complete game; it should not reveal that the promised game was unexpectedly incomplete.
Describe the included content
Name the level, chapter, quest, character, or mode and explain its approximate scope. Players should understand what opens before they confirm.
Open a visible entry point
Once success is confirmed, replace the locked state with an owned state and a clear way to start the content. Preserve that entry point after reload.
Keep the promised game complete
A bonus path can extend the experience, but the core ending and advertised main game should not disappear behind an unexpected purchase.
