Wow, you picked the perfect name for this . It was really Squirrelly
I can see this being built but for me, I felt it would of been a more enjoyable ride if the layout wasnt so tight. I tried both the front seat and the back and noticed esp from the back that you are really thrown all over the place and would be a bit extreme if made in reality. Great design but I feel making it a bit more spread out and not so quickly thrown from one side to another would of been better. But hey, this is just my opinion.
The terrain you incorporated for this was cool. Love terrain coasters.
The 3D work also is very nice and I hope one day to be as good. I'm just now figuring out how to make car textures.
