Very nice submission, congratulations! :)
It felt good to jump on the umbrellas, while constantly trying to avoid birds: it's a cute idea, and creates an interesting contrast with the greyish city around. I appreciated the consistency of the details (like having different colors for different types of umbrellas/platforms). The controls were also really smooth and precise: they were responsive enough to make me feel accountable for every fall :')
The only thing I might suggest is to make some birds more visible... The grey crows were pretty mimetic over the background :)
Great job, enjoyed it a lot!
