I opened the game and walked left and right with the seagull, and I immediately started laughing. This is really cool.
The way you handled the theme is legendary. It turned out to be a really fun game, m_2ne.
You finished the game beautifully. The logic is great: collect and bring it home as quickly as possible without getting caught by the wave.
To increase the playtime, you could do something like give the seagull a little more life time every time it returns to the nest with its hands full.
Anyway, good luck with the jam. If you want to check out my game,
