HELP!!!!! i need help making a maze.

I am trying to use the code from turn base strategy to make a first person random generating maze. I am hitting a few snags.

first I need to make it to were I can increase the size of the map and number of corridors that come out of the rooms

second is that I need to make it to where I can get rid of the 3rd person and make it into a first person without being a turn base system also have it to were only I am put into the game with out other people.

if you could help me with that I would be much obliged.

1)Setup some variables, which I assume it probably already has for this, just check out the procedural generation blueprint and tweak the values in there and see what happens.
2)Change your game mode, pawn and player controller to the first person 1.
