PLEASE READ POST CAREFULLY I’m looking to turn a classic marble concept into a lightweight, competitive 2D mobile game. Players should be able to flick their marble on-screen and knock rivals out of a circular arena, with each quick match deciding the winner. The whole experience must feel snappy, require only one hand to play, and run smoothly on mid-range Android and iOS devices. Core mechanics • 2D top-down arena where physics determines marble speed, spin, and collision outcomes. • Real-time head-to-head mode (quick matchmaking or room code). • Simple touch controls: pull-back power meter, release to shoot. • Win condition: last marble standing or highest score in a timed round. Visual style Flat, colourful 2D art with subtle shadows and highlights—clean enough to keep file size small but lively enough to look modern on Retina and high-dpi screens. Ideal toolset Unity or Godot (I’m open, as long as you can export to both Android & iOS and the physics feel natural). Deliverables 1. Playable builds for Android (APK/AAB) and iOS (TestFlight). 2. Full commented source code and asset folder. 3. Simple lobby/quick-match backend (Firebase, Photon, or similar). 4. One arena, three marble skins, short menu flow, and basic sound effects. 5. Post-launch bug-fix window (two weeks). Acceptance criteria • Stable 60 fps on devices from 2019 onward. • Matches connect and finish without desync in 95 % of test runs. • Touch input maps precisely to in-game force and direction. If you’ve shipped any real-time mobile titles or physics-heavy mini-games, send a link—I’d love to see them and kick this off quickly. { i will share my details once i choose someone ...i hire this work to two developer before they both did not do my work as per my need ...one guy take payment and gone offline permanent and another guy always asking for extra money for each changes i have fix price now and will give once my work 100% done ... changes are the part of work if anyone will not do that then please don't put offer on my post its my request ....}

Hello, With a solid background in mobile development, I bring more than just my technical prowess to the table. I understand what it takes to build an engaging and responsive game, and your unique marble concept aligns with my experience in creating real-time mobile games that emphasize physics and quick match-ups. Speaking of which, your requirement for stable 60 fps on devices from 2019 onward is one of the benchmarks that I'm confident in achieving. In fact, one of my recent projects, a head-to-head racing game, similar to 'marble knocking' satisfied similar performance demands. Lastly, I always ensure a bug-free app when delivering any project. But recognizing software is an ever-evolving process, I offer a generous post-launch bug-fix window of two weeks to finely tune any unforeseen issues and maintain the high consistent quality that we both demand. My goal isn't just to complete your project; it's to exceed your expectations with a durable product.

The key challenge here is making the marble physics feel genuinely responsive while keeping real-time matches synchronized across Android and iOS. I can handle the Unity-based mobile game build, including the flick/power control, collision and knock-out physics, arena flow, marble skins, audio, and multiplayer lobby/match flow. I’d structure the multiplayer carefully around authoritative game-state handling so marble movement and match results remain consistent between players, then optimize the 2D rendering and physics for smooth performance on your target devices. I also noted your fixed-price concern and the previous development issues. I’ll treat the agreed scope and required revisions as part of the delivery rather than turning normal fixes into repeated extra charges. I don’t have an exact marble-game reference in the supplied portfolio, but I can share relevant mobile-app work such as Rajgarhwala Furniture, which has live Android and iOS versions. Share the detailed feature flow and I can outline the implementation milestones before development starts.

You need a snappy 2D marble brawler with physics that feels right, real-time matches that don't desync, and a build that hits 60fps on 2019-era phones. That's exactly the kind of scope my team ships. Most relevant to you: Unity 2D with C# (custom physics tuning for flick force, spin, and marble collisions — not just stock rigidbodies), Mirror/Photon multiplayer for quick-match and room-code lobbies with server-authoritative outcomes to prevent desync, and native Android/iOS export pipelines so your APK/AAB and TestFlight builds are clean on the first pass. My approach: lock the flick-to-force mapping and collision feel in a tight prototype first (this is where most marble games fail), then layer matchmaking and win conditions. I understand your payment terms: fixed price, released only when the work is 100% done to your acceptance criteria, and revisions are part of the job — not an upsell. I won't ask for extra for changes. I've seen how your previous two hires handled this; that's not how we work. I can share real-time mobile and physics mini-game links on request. Ready to start immediately — let's get your prototype moving this week.

The rim is the thing people forget on a knockout marble game. If the circle is a solid wall, marbles bounce around and nobody ever gets eliminated. It has to be a lip. Cross it and you fall out of the round. That plus the pull-back is what I would build first, on one phone, with a few marbles. Friction and a little spin, so a shot travels and then sits still. Pull distance has to fit a thumb, or the player braces the phone with the other hand and it is no longer one-handed. I would leave a second phone out of this build. Firebase works for a room code and a player name. It is not built for a write on every marble every frame, and the lag shows up as a hit that lands late. TestFlight needs an Apple Developer account in your name. iOS can wait until you have played the Android version. I can start tomorrow and send an APK in 3 days. 10000 INR covers that build and the commented source. Can the first build be you alone against marbles that do not shoot back, or do you need another person on a second phone?

You want a polished, physics-driven 2D marble game that feels instant to pick up, runs at locked 60fps on mid-range hardware from 2019 onward, and handles real-time multiplayer without desync headaches. That combination of tight physics, cross-platform export, and reliable networking is exactly where most marble game attempts fall apart, so let me tell you how I would approach it differently. My stack: Unity 2D with Rigidbody2D physics tuned for satisfying marble collision feel, Photon Fusion for deterministic state-sync multiplayer which kills the desync problem at its root, and Firebase for matchmaking and room codes. Unity gives clean Android AAB and iOS IPA exports from a single codebase, keeping your timeline realistic. Plan: Week one covers core physics sandbox, pull-back controls, arena bounds, and collision tuning. Week two adds real-time multiplayer lobby and matchmaking. Week three delivers three marble skins, flat art pass, sound effects, menu flow, and both platform builds. Week four is reserved for device testing across low-end and high-end hardware, performance profiling, and your TestFlight submission. I have shipped cross-platform Unity titles with Photon networking and understand the input-lag and frame-rate traps specific to mobile physics games. What device models are highest priority for your acceptance testing?

Hi, I see you're having trouble with a marble game that needs a stable 60 fps on mid range devices, and I'd approach this by checking the physics engine and optimizing the 2D art for better performance. The real-time head-to-head mode is a challenge, and I'd handle it by setting up a simple lobby backend with Firebase or Photon to ensure smooth matchmaking. I'd also focus on getting the touch controls just right, so the pull-back power meter and release to shoot feel natural. In my experience, getting the physics to feel natural is crucial, and I'd start by tweaking the Unity or Godot settings to get the best results, and then I'd move on to optimizing the code for better performance on Android and iOS devices. I'm ready to start immediately, and I'll make sure to deliver a playable build that meets the acceptance criteria, with stable 60 fps and precise touch input mapping to in-game force and direction.
