M50 Speed Run
Email davidcarrpi2@gmail.com and I'll get back to you. Including your device model and your iOS or Android version helps a lot.
How to play
Drag anywhere to steer -- you don't have to touch the car itself. Tap to boost. Squeeze past traffic to build your combo; the combo builds Heat, and Heat both multiplies your score and brings the police after you.
My progress disappeared
Your best score is held server-side, so it survives reinstalling. Cash, cars and daily mission progress are stored on the device only, the system can clear that storage if the device runs critically low on space, and deleting the app removes it deliberately. There is no backup of the garage, so that part cannot be recovered.
There's no sound
Check the mute toggle in the menu, and check your device isn't in silent mode. Phone browsers and apps only allow music to start after your first tap -- that's a platform rule about audio playback, not a bug, so the soundtrack comes in a beat after you press DRIVE.
It feels slow or stutters
The game watches its own frame rate and automatically reduces visual detail if it detects a struggle. Closing other apps usually helps. Do report it with your device model -- performance problems are worth fixing.
Privacy
The game never asks for your name or email, and shows no adverts. When you finish a run and you are online, it sends that run's score, distance, near-miss count, the car you drove and a timestamp to the leaderboard under an anonymous ID that is not linked to you as a person. The privacy policy sets out exactly what is sent and how to have it removed.
