Ok, I have something to show. So say hello to "random" procedural levels (infinite levels):
I'm using allways the same seed, so each level will allways be the same level.
What I've done is alternate automatic perlin noise terrains with some prefabs I've made (the windmill, boxes, bridges, and a lot I've made). The difficulty is increasing as you go further, so the terrain will be everytime harder and the prefabs will be also harder. Same with fuel cans, everytime further from each other, but the coins will be better as you progress.
So if I want to make a new level, I just have to change the seed, maybe some parameters and that's all!
I've also started to make some GUI and also working on music and sound effects.
A very important thing of this game will be the vehicle customization, it will be time consuming to handle everything, but will be worth the effort, as this is very important to keep the user playing again and again to get more coins and customize the car. Not only physical things, like deposit, grip, engine... but also colors, driver (male or female, maybe even the hair color), tires...
