Thanks for the compliment.
Orion told me that the ram limitation is a real issue which prevents him from adding more frames for the car. But he said he'll look when he has more time if he can change some elements in order to improve the game.
As for me, I had in the beginning lots of ideas like different kind of fx like smoke, detailed explosions and such, but the ram threshold was already reached with what we had.
For example, the car skidding animation is made of 8 frames which uses a lot of ressources. I wanted to add more things, but programming wise, Orion told me there's not enough ram.
