Your ride had some very awkward transitions. Sure, it wasn't newtony. Someone could easily do this with no tools. You love straight geometry and can't make a flowing element, yes, we know that. Heck, you can even do the WHOLE thing in curved geometry. It may not be shaped right, but at least it'll be better shaped then this. Prefabs. Prefab supports everywhere. I appreciate your attempt to make some customs, not enough, i'm afraid.
A: Interesting. Not entirely thrilling. It's a family coaster. Not a thrill ride. A family coaster made really badly. I'm sure you just scared a lot of kids from coasters now because of bruises. Ow. No more straight geometry. They probably weren't that excited anyway.
O: Really, this was nothing like Boulder Dash, nothing like any B&M hyper i know, and nothing original at all. A few badly done turns, a few badly done hills, and that was it. Oh, and a lift hill, break run, and not much else. I wonder who you ripped this off of, anyway?
Of course, don't give up, just don't use use straight geometry. Ever. Or else.
Next ride, i think you should handbuild. Take my advice, kid, and you will get a better ride. Obviously, newton isn't for you.
