Hey thanks a lot for this amazing review! Yeah we definitely have a lot of bugs and areas for improvement! We couldnt find more time to fix them as we created it in 5 days. But based on feedback we are planning to update the game soon! And yeah the car controller was definitely tough to get and I spent a lot of time on that :d,When my friend sent the track he modelled we had some UV issues and so the textures didnt really get applied the right way on the track! Also yeah UI was a last minute job and I agree with that! I should try to make the UI better!
And as far as theme is concerned as mentioned , Less is the speed of the car, more is the fuel consumed!
Anyways thanks a lot for playing and reviewing it in such a great detail!
