Low poly/Retro looks. No mod needed, textures are simply zoomed in. Feel free to expand on this as you need, as I mostly focused on blocks I needed for my own track.

Loops are not made to be driveable, simply to look cool. I guess you can drive them with reactors if you really want to.

The curves of the turns are not the same as the vanilla blocks (My turn 2 is in between base turn2 and turn3). I only noticed after finishing the map.

If you want to edit the items

I made most of the items in Blender, a good part of them can't be edited in game. If you need to edit the items, just ask me and I can provide you with the blender files or make a small changes or two.
