Damn! Very ambitious for a solo-deveploer jam project. I love the lowpoly art style and the the city was so cool that I just stoped racing to explore the enviroment and check you pretty 3d models.
I thought it was really hard to control, but I wouldn't say thats a problem as I am notoriously bad in flying mechanics in general xD. And the controls do feel apropriate to what is expected of flying mechanics.
I would also like to mention that the idea of a crow race is really cool, fits the theme and it is original.
