Finally, you may want to make a new game and leave this behind. Try to make something new from scratch. Good luck, Thelyer, keep going, good game design starts when you keep pushing to learn from your mistakes.

Next the camera, you made the camera clip less because it's harder for the camera to clip, but you did not fix the issue. Right now, play your game, and back up against a wall, the camera will clip. you have to make it so that when it hits a wall, it stop moving in the x or z axis towards that wall. As I said about a year ago, tags are the best way to do that. Now lighting, and this bleeds into the models thing. You're using blocks for everything, which is nice, and it fits well with our idea of a wall, but you should use planes instead. Unity gives you a nice one, and when light shines on it, it has a much, much more fine lighting effect to it, give it a test. Finally, for just bits and pieces. You can disable physics on certain objects, or even movement along an axis. With this game, the cart is only concerned in the x axis, so disable to y and z axis, this will make it literally impossible for the cart to fall over.

So, Better late than never, I suppose. You're taking the time to work on your game, so I'll take time to help you develop it. First off, the music needs to have a toggle. It's cute, but get's old long before 100 seconds are up. Models next, when you're using textured models, you NEVER want them to clip. Not even a pixel. If one wall ends at 1001, the next wall begins at 1002. Clipping is something very off putting to look at, and it matters rather little here, but you should keep it in mind for your next game. Also, when making models, pick a size, let's say "100, 5" that is the size of your wall, and it can be rotated, but it will never be longer than that. See the outer most walls, how bad their textures look? It's because they're stretched way too far.

phyre nailed it on the head! Also the in game driving is not conducive to an enjoyable game experience, maybe if you give a navigation map and widen the lanes...

This... needs work... a lot of work... First off the bloody music, dear lord. Second off, you need to add a script to your camera's movement so that if it hits anything with a "wall" tag, it won't clip it, instead it'll just push up against it. but yeah, needs work.
