Hey, the cave is generated randomly, so each playthrough is unique! The cave is made of parts that are as long as 4 moves, there are 4 different shapes of these cave parts, that fit together when rotated by 22.5 degress, so that's 16 different rotations for one part! This makes the generation look like the cave is never repeating! If you are asking about how the cave parts individually were made, my teammate did the 3D models, so you can ask him directly ;)
