This game is truly fantastic, you guys should be proud of your work and for having completed in the 72h time limit, also.
The only real suggestion I can think of right now is having the wind direction influenced by the surface the cursor's location, eg when going up a ramp, moving the mouse along the ramp the wind would follow it but instead it simply follows the cursor's ray vs a ground plane.
It's a minor gripe and once you understand how it works you can adjust, but for such a minimal input scheme I think polishing it in ways like this really make it play that much better.
Once again fantastic work.
