Rhythm · Content Unlock guide
Build the rhythm loop first, then test one optional rhythm bonus challenge at 75 Koin. This guide focuses on included content, permanent access, entry point, and restore state.
Create this game flow
Focused keyword and player case
Offer the rhythm bonus challenge for 75 Koin only after a safe gameplay pause. Show included content, permanent access, entry point, and restore state before confirmation. Cancel and insufficient balance must preserve progress; success must deliver once and remain correct after reload.
Use the focused content unlock hub for an authentic screenshot, direct playable result, and the complete purchase-state checklist. Gameplay evidence supports placement testing; it does not prove a live transaction.
Give design, UI, and QA one shared item definition. Everyone should use the same benefit, duration, Koin price, and ownership rule.
A rhythm browser prototype centered on music readability, timing feedback, and expressive themes.
A content unlock preview with a concrete description and direct Koin price.
Place the content unlock after this loop advances: a rhythm browser prototype centered on music readability, timing feedback, and expressive themes. Wait for a safe pause. Player progress must not depend on the offer.
Offer-card rules: Preview without muddying timing; Describe the included content. Show the item, benefit, ownership or duration, balance, and full price in Koin. Keep confirm and cancel separate.
Test preview, confirm, insufficient balance, success, mark the purchased content as owned and open its entry point, and reload. Show that change inside normal play instead of relying only on a success message.
Test a free session around a rhythm browser prototype centered on music readability, timing feedback, and expressive themes. If play becomes incomplete, fix the game before changing the offer.
Place the choice on track select, customization, or results screens. Never cover notes, timing judgments, combo feedback, or the short countdown before performance begins.
Demonstrate themes, note skins, trails, or effects against real chart motion. Confirm that colors, flashes, and animation do not reduce beat readability or create an accessibility problem.
Cancel and return to the same song, difficulty, modifiers, and input setup. Once buying is complete, place the item in customization and verify it stays equipped after another performance and reload.
This rhythm game uses a rhythm browser prototype centered on music readability, timing feedback, and expressive themes. Review the genre through wait until the song ends and preview without muddying timing. For a indie studio, the content unlock should support that loop without becoming mandatory. Review the item through describe the included content and open a visible entry point. An indie studio can divide timing, interface, implementation, and failure testing among named owners. 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. Select a song, difficulty, input layout, modifiers, note speed, and accessibility settings, then finish one chart before visiting customization. Cancel and return to the identical track setup with focus restored. Try insufficient Koin without starting the song or changing timing options. Complete a valid theme, note skin, trail, or content choice and preview it against moving chart elements rather than a static thumbnail. Play the same song and review contrast, flashes, judgment readability, latency perception, and combo feedback. After results and a fresh load, verify the item stays selected, settings remain stable, and no purchase layer can overlap notes or the countdown.
Design owns the offer timing and free path, UI owns readable states, engineering owns state transitions, and QA owns failure coverage. Agree on the same item definition before anyone creates implementation tickets.
Use the prototype in a short team session and walk through decline, insufficient Koin, pending, success, delivery, and reopening. Resolve player-facing disagreement in the build instead of leaving it inside separate documents.
After the journey is approved, split identity, durable ownership, native billing, security, refunds, policy, localization, accessibility, and analytics into explicit work. The prototype should not be treated as proof that those systems exist.
Have a tester interrupt confirmation, repeat an input, change screens during delivery, and reload at several points. Compare the result with the agreed item promise and reject duplicate grants or unexplained Koin changes.
Schedule a short session with design, UI, engineering, and QA using the same playable link and item definition. Assign one person to operate while the others record disagreements about timing, wording, delivery, fairness, and recovery. End with an explicit decision for each disputed state and name the owner of every native implementation task. Update the prototype or source brief before tickets spread outdated assumptions. QA should then write independent scenarios from the agreed player promise, including interruption and duplicate input. This creates a shared reference without mistaking the browser build for a backend, billing integration, revenue forecast, or release approval.
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.
Name the level, chapter, quest, character, or mode and explain its approximate scope. Players should understand what opens before they confirm.
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.
A bonus path can extend the experience, but the core ending and advertised main game should not disappear behind an unexpected purchase.
Make the main activity playable before adding the content unlock. Players need context to judge whether the item is useful.
Result: A working rhythm foundation
A content unlock preview with a concrete description and direct Koin price. Keep the same wording in the preview, confirmation, and delivered state.
Result: A consistent player promise
Show the exact Koin amount, current Koin balance, confirm, cancel, and what ownership means. Design chooses the offer moment, UI makes every state distinct, and QA tests transitions and recovery. Use the playable prototype during the team review.
Result: An understandable decision
Test preview, confirm, insufficient balance, success, mark the purchased content as owned and open its entry point, and reload. Then test an insufficient balance, cancelling the action, repeated input, interruption, and reload.
Result: A visible, stable result
Write test cases for not enough Koin, a player cancellation, delayed delivery, repeated input, and reload. Create production tickets only after the player journey is agreed.
Result: Indie studio plan
Create a browser-playable rhythm game prototype for a small indie studio. Build the core loop around music readability, timing feedback, and expressive themes. Add one optional content unlock offer containing a bonus chapter card with scope, Koin price, ownership state, and launch action. Price it directly in Koin, require an explicit confirmation, show the balance effect, and mark the purchased content as owned and open its entry point. Do not add subscriptions, external payment checkout, revenue reporting, or guaranteed earnings. Include insufficient-Koin, cancel, success, and reload states.
Keep the item optional. Show its full price in Koin, visible Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
State the exact item, included content, permanent access, entry point, and restore state, and the full 75 Koin price before the player confirms.
Use a natural planning, customization, or post-session moment. Do not interrupt active controls or make ordinary progression depend on opening the offer.
The free-game progress must remain intact, and a successful purchase must restore the same owned item, content, quantity, or capacity without another charge.
