Above: Old version, before Sky Kingdom was introduced
Below: New version (rough drawn), update 9.50
1. #50 Ooka Ooka Shrooms doesn't go to #67 Plant Swamp, though #48 Mush Cave does go to #67 Plant Swamp.
Also wrong lines are 2. connecting Future Water Trench instead of Light Highway and Wastelands Entrance, 3. no line connecting Shroom Slide and Ice Lake, same as 4. with Wastelands Maze and Wasted Plains and 5. I think Beauty Hillside has one or two more connection(s) to another room. 6. Sky Kingdom wasn't added yet 7. Clicking the dots doesn't work anymore
