Utterly broken and abandoned
The main reason to use the app is obviously the track editor - which was already a horrible messy experience - but now it’s really completely broken. So much that the cars won’t even make the turns. They just ignore the first corner of any type of track you build and go straight until they leave the track an stop. The recover button to put it into the track again doesn’t work. There is also no sound or music when running on your own tracks. Reinstalling does nothing. The last update was more than one year ago. It’s basically abandoned.
