I had forgotten to take note of the proper hue/saturation to use in order to make the yellow tiles for the 'caves/surface' tileset, so I had to redo them all. I'll have to be a bit more careful in the future, because it's easy to lose a few minutes messing around with that thing. I'm moving along with the creation of new rooms, but I'm a bit dreading 5-4-1, which is identical to all of the other 4-1s as it contains the boss rematches.
I feel that room 4-1 should be the same, no matter in which State you are, but this causes a few problems, for instance if you quit the game in that room, I wouldn't be able to statically remember where you came from. I would have to save that somehow, and I'm not sure I want to. The main reason why I don't want to reproduce 4-1 ten times is because it's a room I'll tweak often and I don't want to have to do it 10 times each time.
Time spent on the project so far: 447 hours
