Here is a fun test, something close to my heart was making an easy way to create a dungeon. It's not perfect cause the walls are slanted instead of vertical. Not sure yet how you fix that but this is another 1*1 test. The corridors are also way to small to be gameplay ready so there is that to deal with but still, not a bad result for a first try.
