Really good for a first game, well done! The vibrant visuals and clean models made up for the more rudimentary movement physics, especially with the jumping. You had some nice ideas for platforming and the updraft mechanic has potential, but I'd encourage you to further make use of the spherical nature of your player character.
Also, as another person mentioned about Linux, the game doesn't actually run on Mac either. Mac can only run .app-type games, not .exe's. But I managed to emulate the executable, so there's no problem. Thank you for the experience!
