Yeah I can see that... I wouldn't even know where to begin with 3D-procedural generation on that short timeframe - especially when it's not just a 2D maze build up but has stuff to jump over etc...
this version is actually simple , you put two loops with x and z on one loop to make a grid, and you instantiate your prefab ( i cheat by putting some blocks at higher probabilities spawning so you always have a path( there is none algorithm on this procedural lol ).
