Really nice to see you're working on a track again, Thomas. I love the setting - this could get really great.
But I already have some brain food for you: What are your plans regarding dinosaurs? The Re-Volt engine is not really made for adding living creatures. If you don't plan to add dinosaurs in any way: How do you think you will reach the atmosphere of the dinosaur age, without having actual dinosaurs in it? I just thought about typical stuff you could place around the track, but somehow no things come to my mind. My fear is, that the tracks "just" feels like a jungle-/biosphere-map in the end. For sure, some frightening ROAR
sounds in the background can add some atmosphere, but I don't know if this would be enough. Would be really interested, how you plan to solve this!
Good luck with the track, I will for sure follow your process.
