How do leaderboards work?
Platinum and Ultra track your best times per level and submit them to global leaderboards. You can view rankings in-game or on the web dashboard. Your times are automatically synced when you finish a level while connected to the internet. If you get a world record, your replay is also submitted.
Can I play custom levels?
Yes! Platinum supports thousands of community-made levels from the Marble Blast Community. You can play these levels in-game from the level selection menu. Ultra includes a curated selection of custom levels. These custom levels are available for both Singleplayer and Multiplayer. Gold currently focuses on the official campaign.
How does multiplayer work?
Platinum and Ultra support cross-platform multiplayer across Windows, macOS, Android, and browser. Create or join a lobby from the multiplayer menu, and friends on any platform can join. The game uses client-side prediction with server reconciliation to keep gameplay smooth.
How do I transfer progress between devices?
This capability is only fully supported in Ultra. You can back up your progress through Options > Import & Export, and restore it a different device through the same menu.
How do I change resolution or FOV?
In the browser, resize the window or use zoom. Native builds let you resize the window. FOV can be adjusted in the Options menu for Platinum and Ultra; for Gold, you can edit <code>settings.json</code> to fine-tune FOV.
How do I unlock FPS?
The browser target is VSYNC locked. Native versions can unlock FPS through the in-game Options menu or by editing <code>settings.json</code>.

Where can I adjust camera sensitivity?
Camera sensitivity can be adjusted in the Options menu under Controls.
I'm unable to join multiplayer lobbies. What gives?
Make sure your firewall or antivirus isn't blocking the game. Additionally, ensure you're running the latest version, as outdated clients may have trouble connecting.
Why does a level load to a black screen?
Your GPU may not support the rendering features the game relies on. The workaround is to play on another machine or via the browser build.
Where do I report bugs and crashes?
Please contact us on Discord and create a detailed issue report on GitHub including your OS, steps to reproduce, and any relevant logs.
Can I request new features?
If it existed in the original game titles but not in this port, open an issue or PR once you've built a prototype. Otherwise, feature requests are handled case-by-case.
