Please use texture smoothing or something like that, things like the water slide are unbearably bumpy, some cars are hard to get into the slides/tubes, some parts of the first few green pipes are misaligned and the cars tend to get destroyed on them, the roads are just textures of roads with dirt beneath them, really everything's pretty low quality or low poly like this map was meant to be half the size, however I do love the idea and how the mountain roads flow. I hope you keep working on this, if those things were fixed it'd be a 5 stars easy.
I love this map. It has a hundred ways to destroy even the toughest vehicle. The only thing I've adjust is the interface between the platform and some of the tubes so you could inch right up to it before coasting down.
I was kinda thinking it was a Death Fall ripoff... But then I saw you are the guy who made Death Fall! And I also saw the video and it looks awesome! It just looks like Death Fall but better, more variety and crazy stuff! Everyone likes destruction maps like this, good job on this one!
