Nice submission and well done for creating the assets by yourself, that's a big ask for the timeframe provided! I really liked the feel of the game and the way the music/sounds coupled with the controls to give that feeling of flight. I would have maybe liked something like a minimap to show the surrounding area as sometimes I jumped off after looking down and then the way I went didn't have anything I could land on as the finish was in the other direction.
Only a minor recommendation though as on the whole I felt everything came together well and it was a joy to play! Nice work :)
