Beta Desert Highway 2021.12.29

Hey guys, took a couple hours today to fix up some stuff you've been bugging me on (all good things, keep doing this!)

Changelog:

• Fixed many road-to-road transitions. Many roads were badly overlapping.
• Fixed some unrealistic bank curves on the hill climb portion, some areas had banks up to 25 degrees. These have areas have been vastly normalized and have had signs added.
• Fixed water. The physics were broken on the lake and on the river. Deleted these and remade them and the physics are working. Darkened the water a bit and made the ripples flow in the logical direction.
• Fixed/removed some areas with vegetation on the road.
• Added multiple preview pictures for a mini slideshow in the level selector.
• Updated preview picture.

Enjoy! Let me know if anything is broken
