The problem with big birds in my game is that when it comes to the part of the vine you're on, you have nowhere to go. So I made the bird small again. I also figured out that I can only have 36 (255/7) screens for the stalk. And less than that since I need to free up part of that to fit in the code to draw the grid. So I will try to have 30 different screens. And have the castle consist of 30 screens as well.

I found and fixed a bug pertaining to down movement. I did something similar to the castle part I'm thinking of doing on the Odyssey 2: I did a thing I never finished called "Haunted House". That screen had a multiple story building in it. Idea: I could have the castle be multiple stories as well. 3 times 30=90 so I could make the castle be at least 90 separate screens. More if I decide to be daring enough.
