While functional, wind could be giving a couple tweaks to make it more robust.

If you make wind too strong you get push with no way of fighting against it. Make it too low and you won't get blown at all and only get slowed down when walking against it. At lower speeds wind should actually push Tux slightly when standing

It feels to me that wind, instead of pushing Tux, it gives him a set amount of speed in a specific direction, resulting in it feeling very unnatural!

Also, another idea I had regarding wind:

An underwater object type for the wind object, Current, that instead of wind particles uses bubbles.
It will function nearly identical to wind, however I assume it may require some slight adjustments for the underwater setting.

EDIT: Current was implemented by #3270 as a wind with different particles.

Some of these things maybe be:

• Dive Mine is unaffected by it (this allows for fun dodging underwater)
• You have better control within the current for better navigation and correcting
