Hello,
It's been a few weeks since last update. I wasn't able to find as much time as I wanted to improve the game. However, future patches will come quicker.
For this patch, I fixed flying cars bug, added a new feature, and improved game back-end (has no effect on game, just useful for upcoming patches).
+ You can now change interior color of your cars!
+ Flying cars bug fixed.
+ Backend improvements for future updates (no gameplay impact) .
Hope you enjoy the new feature.
