Id recommend duplicating your BSPs individual components and moving to a spares folder before converting to static mesh so you can make fixes without remaking the entire maze (might be good practice).
there’s a good chance you might discover an issue later for example the ball clipping as explained later in the videos, clamping works but too much and it makes the maze lethargic and less enjoyable also apparently making the walls and floor thicker works however I didn’t test this.
I built my maze with shorter walls on the inside (still twice the size of the ball) and am now able to jump to the end over the interior walls. id like to add a glass ceiling to see if that would take remaking the map
I will say there is probably other solutions but this all I can think of at this stage of learning
