Frequently asked

The game won't start / shows a GPU error. SunaBox needs WebGPU-class graphics. On desktop that means an up-to-date Windows, macOS or Linux machine with current graphics drivers. The Steam build ships everything else it needs.

Something looks wrong after an update. A full restart of the app (or a hard refresh, on web builds) clears mixed-version caches. If it persists, email a screenshot — screenshots of bugs are gold.

Can I open my old OE-CAKE files? Yes — drag any .oec scene in. SunaBox reads all four historic versions and reports honestly what it could and couldn't reproduce.

Where are my saves and replays? Scenes save as .suna files and replays as .sunar — ordinary files you own, small enough to share anywhere. A replay reproduces your session bit-for-bit on any machine.

Refunds Steam purchases follow Steam's standard refund policy, handled entirely through Steam.

Found a bug? Have an idea? Email it. Include what you did, what you expected, and what happened instead — replays (.sunar) attached to bug reports are the fastest possible path to a fix, since they reproduce exactly.
