FAQ
What types of Unity bugs can you fix?
I can help with gameplay bugs, C# script errors, UI issues, crashes, build problems, animation-related issues, broken interactions, logic errors, and other Unity project problems.
Do you work with both 2D and 3D Unity projects?
Yes. I can debug and improve both 2D and 3D Unity projects.
Can you optimize my game if it has low FPS or performance issues?
Yes. I can investigate performance bottlenecks, unnecessary processing, inefficient gameplay logic, and other issues that may affect FPS and overall stability.
Do I need to send the full Unity project?
For many issues, access to the relevant project files is the fastest way to diagnose the problem. For simple errors, screenshots, logs, or specific scripts may sometimes be enough.
What should I send before ordering?
Please send a short description of the problem, screenshots or video if possible, error messages or logs, Unity version, and any other details that help reproduce the issue.
Can you work on an existing codebase without changing everything?
Yes. I focus on fixing the specific problem while keeping the existing project structure intact whenever possible.
How many bugs are included in one package?
The Basic package is intended for one minor issue. More complex or multiple connected problems should be discussed before ordering so I can recommend the correct package or custom offer.
Can you fix build errors for Android or other platforms?
Yes, I can investigate Unity build errors and project configuration issues. The exact scope depends on the error and target platform.
Will you explain what was fixed?
Yes. Standard and Premium packages can include fix documentation explaining the issue and the solution applied.
What if the issue is more complex than expected?
If the problem requires significantly more work than the selected package covers, I will explain the situation and we can agree on a custom scope before continuing.
