Initially, I was extremely nervous about working with a designer, unknown to myself and trusting the process to deliver what I expected. Billi was amazing, incredibly patient and talked me through the process, once he even recorded a step by step video so that I could set up my part of the project. I would definitely work with Billi again, I wanted to give up many times but he made it easy. It's been a very enjoyable learning curve!
This developer is truly amazing. I have never met such a skilled and kind developer before. He listens carefully to every requirement and makes sure to complete everything exactly as requested. His communication is great and he is very patient and supportive. The game he delivered for me is high quality and works perfectly. I really appreciate his dedication and hard work. Highly recommended — one of the best developers I've worked with ❤️
It was my first experience on Fiverr and the first time I used Admob and this developer helped me a lot from the stage of creating the game to publishing, thank you my friend and I will come back to buy other services.
Great work!! I'll definitely work with him on my future projects.
Billi is one of those rare developers who genuinely cares about your project. He went far beyond what was asked — suggesting improvements I hadn't even thought of and delivering a polished, well-coded Unity game. The whole process was smooth and stress-free. Absolutely will hire again for my next project.
Outstanding experience from start to finish. Billi took our rough game concept and turned it into a fully working Android and iOS title with smooth 60fps performance. He was always available, answered every question, and even helped with the Play Store submission. Truly a 5-star developer.
Honestly, the experience with this studio was beyond all expectations. Exceptional professionalism, impressive attention to detail, and complete clarity throughout the work process. If I could rate them 50 stars instead of 5, I truly would, because what they delivered goes far beyond a normal review. They work with honesty, commitment, and a deep understanding of what the client needs. You can work with them with full trust and peace of mind — they deliver more than expected and with outstanding quality. I’m truly proud to have worked with them, and I highly recommend them from the heart.
Thank you for this excellent work. I have worked with you several times, and I am always certain that you are the best.
Excellent experience with the team. Very knowledgeable, fast turnaround, and most of all, very patient and friendly. Hope to work with them again.
I had a fantastic experience working with this team. From the beginning, they were professional, communicative, and fully understood what I was looking for. The quality of the work exceeded my expectations — everything was delivered with precision, creativity, and attention to detail. They were also very responsive to feedback and made adjustments quickly and efficiently without hesitation. The final result was exactly what I envisioned, if not better. It's rare to find such dedication and consistency. I highly recommend this team to anyone looking for top-quality service. I will definitely be back for more projects. Thank you again!
Everything you need to know before starting your project.
Yes, absolutely. If you’re new to this, we’ll walk you through everything — setting up your developer account (Google Play / App Store) and your AdMob account for monetization, then handling the full build and submission process until your game is live. By the end, your game is published under your own accounts, your ad account is connected and ready to earn, and everything is fully yours. No technical experience required on your part.
Yes. Once the project is complete and final payment is received, 100% of the source code and assets are transferred to you — no licensing fees, no strings attached.
Absolutely. We’re happy to sign a non-disclosure agreement before any project details are shared, so your idea stays protected.
It depends on scope. A hyper-casual prototype can be ready in 1–2 weeks, while a full game with monetization, multiplayer, or custom systems typically takes 4–8+ weeks. We’ll give you a clear timeline during the proposal stage.
Payments are split across milestones tied to development progress, so you only pay for work that’s been delivered and reviewed.
Yes. Every project includes a post-launch support window for bug fixes, and we’re available for ongoing updates and new features afterward.
Android, iOS, and web — including platforms like CrazyGames and YouTube Playables. We can target multiple platforms from a single Unity project.
Yes. We regularly take over existing projects — fixing bugs, optimizing performance, or extending features — even if we didn’t build the original codebase.
