Thanks!
There is a game mechanic that damages you if you don't grab a cookie
![Joker :joker:](./images/smilies/ms-ysosrs.png)
. It is symbolized by the description and red countdown near your hearts. There is also a wind whooshing sound effect that plays if that countdown reaches zero. But if you do grab a cookie the countdown resets with an added one second delay.
It may be this that is damaging you even if you are not touching one of the white squares. These are the only two ways you can get damaged, unless there is a bug.
Extra explanations as to why I made it that way if you are interested:
I made it this way so that people would be more encouraged to chase the cookie not only to score points, but also to avoid damage and take more risks with their moves. As opposed to being super careful or staying for too long in a position. On top of that, eating the cookie is also rewarding because you get health back and if you are doing well enough you get extra protection and score more points with chain multipliers. But this automatic freezing winds damage is more forgiving, because you don't lose combos or chains if damaged by it which increases your chances of getting life or shields back. So avoiding snow flakes is more important.
Hopefully it creates this juggling act where you can't stay still for too long to avoid damage, you may need to take bigger risks that may lead to more punishing damage, but it may lead to better rewards and increase your survivability that gives you more chances to be risky.
