I made some more progress on Clock Town. You can definitely tell they went all out when they were designing it, because there are all kinds of complex texture things going on throughout the town. With all the little ornate shops in town and the boatload of NPCs, this map will probably take me the longest out of anything else in the game, so please bare with me. A nice little plus, though, is that all the different sections of Clock Town fit together perfectly. I'll be sure to take advantage of this fact when producing the top-down view map.
Also, here's a little detail in the game I never noticed before: in the Laundry Pool, there's a group of three fish. On the first day, one is purple and two are gold. On the second day, two are purple, and on the final day, all three are purple.
