The bird looks really good, and I love the shiny green color. The music is serviceable. Impressed by the functional minimap.
There isn't a whole lot going on in terms of gameplay though, and the featureless landscape is not all that compelling. I know that it's hard to know what to do first when you have so little time, and the background is never the top priority.
Thanks :-) I got a bit stuck with some issues between rigging animations in Blender and the way they worked in Unity. If I hadn't spent all that time trying to sort it out, there would have been quite a few more features. But the key thing is that my goal for the jam was to rig a model in Blender for animation in Unity and get it working. I (eventually) learned what I need to :-)
