This is so good. Best feature is you can share your car designs and use other people's. Gameplay mechanics is by far the best out of all the racing games i played in mobile. The power saving mode which activates when you afk for a minute is also really helpful, keeps my phone temp at a normal level. There's also a bunch of other features which i dont want to bother mentioning. The game is pretty optimized i get lag spikes sometimes but not to the point it becomes unplayable. My processor is Helio G96, which is a right about mid-low range in today's standards.
