Frequently asked questions

Are the games really free? Do I need an account?

Yes, all of them are free to play in your browser, with nothing to install and no sign-up. Your scores and Skill Lab progress are saved on your device. If you’re 13 or over you can sign in to save your progress to your account as well.

Why did my Skill Lab progress disappear on my iPhone?

Your progress is saved in your browser, not on our servers. Safari on iPhone and iPad deletes a website’s saved data after 7 days of using Safari without visiting it, unless the site is on your Home Screen. Progress that has already been deleted can’t be brought back. To keep it from now on, add Street 05 to your Home Screen (Share, then Add to Home Screen), save a backup file from the Skill Lab’s “Keep your progress” section, or, if you’re 13 or over, sign in and turn on “Save progress to your account”.

Can we hire Street 05 Studio for bespoke engine extensions or gameplay microgames?

Yes. Beyond public Asset Store tools, our engineering team regularly builds custom proprietary editor tooling, CI/CD test automation harnesses, and custom gameplay systems for independent and mid-scale game studios. You can configure a scope estimate directly in our Project Estimator.

Are Street 05 tools compatible with Unity 6?

Yes. Street 05 tools are built and tested against Unity 2021.3 LTS, Unity 2022.3 LTS, and Unity 6 (6000.x). We utilize compile-time version preprocessors (#if UNITY_6000_0_OR_NEWER) so upgrading your Unity editor version is designed not to break existing scene hierarchies or serializations.

Is full C# source code included with purchases?

Absolutely. Every package purchased on the Unity Asset Store includes 100% readable, unobfuscated C# source code with XML docstrings and clean SOLID architectural design. We ship zero pre-compiled DLLs, zero black-box native plugins, and zero third-party dependencies.

What does "Zero Runtime Allocation (0 B GC)" mean for my game?

In production mobile and XR titles, Garbage Collection (GC) spikes trigger frame pacing drops and stutter. Our runtime modules (such as DevDock and Mobile Device Simulator in-game overlays) utilize pre-allocated ring buffers and Unity UI Toolkit with custom vertex builders, designed to avoid managed heap allocations during gameplay.

How do updates work, and what are the licensing terms?

Purchasing a tool from the Unity Asset Store grants a perpetual commercial license for unlimited commercial and personal projects. All future compatibility updates, performance optimizations, and feature additions are 100% free for the lifetime of the asset via the Unity Package Manager.

Do you offer educational or student discounts?

Yes! We actively support university students, game design educators, and accredited research institutions. Eligible students and faculty can receive a 50% discount voucher across our asset catalog. See our academic page (street05.uk/academic) or contact us with your .edu credentials.
