FAQ
Can you work on an existing Unity project?
Yes. I can join an existing Unity project, understand the current codebase, implement new gameplay features, improve existing systems, fix bugs, and optimize performance without rebuilding the whole project from scratch.
What types of 2D games can you develop?
I can work on different 2D mobile game genres, including puzzle, casual, card, strategy, arcade, and other gameplay-focused projects. My experience includes puzzle, poker, and strategy games.
Can you create custom gameplay mechanics?
Yes. Custom gameplay systems are one of my main strengths. I can implement mechanics such as player interactions, progression systems, puzzle logic, turn-based systems, scoring, combat logic, and other custom game features.
Do you provide the source code?
Yes. Source code is included in all packages. I focus on clean, maintainable C# code so the project can be expanded and improved later.
Can you optimize my Unity game for mobile devices?
Yes. I can help improve mobile performance, optimize gameplay systems, reduce unnecessary load, fix performance issues, and make the game run more smoothly on Android devices.
Can you integrate UI and animations into the game?
Yes. I can implement and connect UI systems, buttons, menus, gameplay feedback, and integrate provided animations into the Unity project. Custom art and animation asset creation are not included unless agreed separately.
Can you develop a prototype or MVP before building the full game?
Yes. A prototype or MVP is often the best way to test the core gameplay mechanic first. I can build a playable version with the main mechanic, basic UI, and core systems before expanding the project.
Do you fix bugs and errors in Unity projects?
Yes. I can investigate gameplay bugs, logic issues, UI problems, build errors, and performance-related problems in existing Unity projects.
What do you need from me before starting?
Please send a short project description, gameplay requirements, references, existing assets or source files if available, and any technical requirements. For larger projects, it is best to contact me before ordering.
Can you work on larger or long-term Unity projects?
Yes. I have experience working on mobile game projects lasting several months, including projects with complex gameplay systems and scalable architecture. For larger projects, I can prepare a custom offer based on the scope and timeline.
