Thanks for the feedback!
When you say that the text went funny do you mean that the two tutorial prompts overlapped? or was there another bug?
With the pigeon having kinda evil aura about the puzzle itself, I am leaning more on that in the future as I rework the level into a new form. The idea is to make a perhaps humorous contrast between the evil looking puzzle and the cute pigeon, which is kinda how I feel about what people say about pigeons: "oh they're gross and they're basically like rats with wings" but actually they're cute and innocent.
I will also work on the bird sounds for the next sprint, and get them to make sounds when discovered, periodically, and such. Also a good point about the ending needing to take away control and present something special. I will definitely bear that in mind for the future as I move into making new stuff on the content side of the development.
