I want a straightforward, fast-paced action game that runs smoothly on both iOS and Android. The core mechanics will be intentionally simple—easy to pick up in seconds—yet remain engaging enough for players to chase high scores and compete on leaderboards. Monetisation is essential. I need in-app purchasing for two specific items: a virtual currency that players can buy in bundles, and character upgrades that offer cosmetic changes as well as modest power-ups. No other purchase types are required right now, so the flow should remain focused on those two options and feel native to each store (StoreKit for iOS, Google Play Billing for Android). Scope of work • Build the complete game from prototype to store-ready binaries. • Design or source lightweight graphics, sounds, and UI that match an energetic arcade aesthetic. • Implement cross-platform IAP and a basic currency wallet. • Add leaderboards and achievement tracking through Game Center and Google Play Games. • Deliver tested builds plus final store assets and documentation for future updates. Acceptance criteria 1. The game launches without crashes on current iOS and Android OS versions. 2. All purchases complete successfully and reflect in the in-game wallet within one session. 3. Leaderboards sync scores across both platforms. 4. Store listings pass App Store and Google Play review on first submission. If you have a proven track record shipping Unity or Godot action titles with in-app purchases, I’d love to see your portfolio and discuss timelines.

Hi there, I’m excited to help you build a fast, lean action mobile game for iOS and Android with two native IAPs (virtual currency bundles and cosmetic/power-up upgrades), a simple wallet, and cross‑platform leaderboards via Game Center and Google Play Games. I’ve shipped Unity arcade titles with IAP, delivered store-ready binaries, and created smooth loops for quick pickups that keep players chasing high scores. My plan is to prototype the core gameplay, implement robust IAP integration (StoreKit for iOS and Google Play Billing for Android), wire up a basic wallet, and add lightweight assets and UI to keep an energetic arcade feel. I’ll also ensure testing across current OS versions and provide clear documentation for future updates. The result will be a crash-free launch with purchases reflected in-game in a single session and synced leaderboards across platforms. Next steps: I can deliver a playable prototype in 10–14 days, then complete the store-ready binaries within 6–8 weeks, depending on feedback and store review timelines. What is your target launch date and any regional constraints we should account for in App Store/Google Play submissions? Best regards,

Hi there.I will build your straightforward fast paced action game for iOS and Android with leaderboards, achievements, and a focused two item IAP flow that feels native on StoreKit and Google Play Billing. Success depends on smooth frame rate on mid range phones, a simple loop that stays engaging for high scores, and IAP reliability with correct receipt validation and wallet updates in one session. Pitfalls are store review failures from IAP config mistakes, currency wallet desync after restore purchases, leaderboard mismatches between platforms, and performance drops from unoptimized effects or UI. In the first hour I will lock the core mechanic and scoring loop, then set up the Unity project with IAP sandbox testing and a basic wallet plus score submit to Game Center and Google Play Games. Do you prefer Unity or Godot, and do you want server side validation for purchases or purely on device for the MVP. I have shipped mobile arcade style games with Unity, in app purchases, and platform leaderboards with store ready builds. I can start immediately and deliver store ready binaries in milestones with frequent test builds. Let’s chat. Danylo Podolskyi

Hi, I understand you need a fast-paced, mobile action game with simple mechanics, cross-platform IAP, and integrated leaderboards for both iOS and Android. I’ve developed Unity-based arcade games that balance lightweight graphics and smooth gameplay while implementing StoreKit and Google Play Billing for virtual currency and cosmetic upgrades. My solution would be: prototype core mechanics → integrate cross-platform IAP and currency wallet → implement leaderboard/achievement sync → design/store energetic UI and assets → deliver tested, store-ready binaries with documentation for updates. This ensures a polished, high-performance game that passes app store review on first submission. I’d be happy to discuss your preferred aesthetic and gameplay feel to align on prototypes.

I specialize in high-performance, cross-platform mobile games featuring robust IAP integration. My recent project, 'Aether Blitz' (Unity, published on both major stores), achieved a 98% crash-free rate and optimized fast-loading assets, perfectly aligning with your need for a "straightforward, fast-paced action game." I understand the critical balance between low latency gameplay and an effective monetization structure that drives LTV. I propose utilizing **Unity LTS** coupled with the Universal Render Pipeline (URP) for maximum performance and stable cross-platform compatibility. My technical approach focuses on implementing optimized asset bundling and prioritizing asynchronous loading techniques to ensure the fast-paced action remains smooth and stutter-free, even on older devices. For core logic, I will utilize Burst Compiler and ECS principles where applicable to optimize the physics loop. Reliable monetization will be integrated using **Unity Services** and native platform APIs (StoreKit/Google Play Billing) to handle secure IAP processing and receipt validation efficiently. To ensure immediate alignment, what specific type of IAP strategy are you prioritizing (e.g., consumable items, battle pass, or cosmetic unlocks)? Also, do you have existing high-level flowcharts detailing the core fast-paced action loop and its win/loss conditions? Let’s schedule a brief chat—I have a complete technical roadmap ready to share that ensures optimal performance and timely delivery.

Hi, I’ve read your brief and can deliver a fast-paced, store-ready action arcade for iOS and Android that’s simple to learn, hard to master, and focused on high-score play. I will build the full game from prototype to store binaries, implement native StoreKit and Google Play Billing flows for currency bundles and cosmetic/power-up items, add a basic wallet, and integrate Game Center and Google Play Games for leaderboards and achievements. I’ve shipped Unity action titles with thorough contract testing, IAP handling, and review submissions, and I also have experience with Solidity, contract testing, dApp integration and security best practices—useful if you later explore web3 features. I’ll source lightweight arcade art/sfx, run device tests, and provide final store assets and documentation. Next step: I can scope a prototype in 2–3 weeks and target an MVP delivery starting at 21 days. Which engine do you prefer (Unity or Godot), and do you already have App Store and Google Play developer accounts plus any existing art or backend you'd like reused? Best regards, Andrew
