Support for Neon Current. Help with racing, City Tour, purchases and saved progress.
Email membrain.app@gmail.com. Include your device model, iOS version, game version and what happened. Remove personal information from screenshots. Never send passwords or payment-card details.
Your boat accelerates automatically. Hold the left or right side to turn, build charge, then release to burst. Sliding across the center changes direction and resets the charge. Open the pilot’s guide from the harbor or Settings for help.
The six Glasswater courses are free, with unlimited attempts. Daily Current and Archive entries set in Glasswater are also free. Dates in other districts require City Tour.
One permanent purchase grants access to the original five districts and 30 total courses, including the six free courses. Districts, boats and cosmetic rewards are still earned through play. There is no subscription. Future expansions, if offered, are separate purchases.
Finish four different courses in your current district to open the next. Repeating the same course does not count as another distinct finish.
Connect to the internet, open Settings, select City Tour, and choose Restore Purchases. Use the Apple Account that purchased it. Restoration restores content ownership, not progress from another device.
The app could not load City Tour from the App Store. Continue playing Glasswater and try again while connected. During prerelease testing, purchases also depend on the test distribution and purchase configuration. If the issue continues, email support with the version and message shown.
Yes. Your available courses work offline. Buying or restoring City Tour requires an internet connection.
Progress, settings and personal ghosts are saved on this device. There is no game-managed cloud synchronization. Deleting the app can remove local progress. Restoring City Tour restores access, not race records.
Each UTC date selects an authored route, boat and fixed current conditions. Retries use those same conditions. Archive lets you revisit earlier dates, subject to district ownership. This is a personal racing challenge, not live multiplayer.
Settings includes the left/right touch-zone split, reverse steering, reduced effects, personal ghosts, music volume and engine/effects volume. Device Reduce Motion is respected. Pause a race to resume, restart or return to the harbor.
